Molar Mass Of Butane Lab Report

598 Words3 Pages

Conclusion
The aim of this experiment was to find the molar mass of the butane using the gas produced by the lighter. The lighter produces the butane gas and the volume of gas released and the mass change of the lighter are used to calculate the mole and the molar mass of the butane. To calculate the molar mass, the Ideal gas law, PV=nRT is used. The theoretical value of the C4H10 is 58.12g/mol. However, the experimental value that I could get from the calculation was 51.46g/mol for the molar mass of butane. This indicates the percentage error of 11.46% has occurred in the experiment with possible errors.

Evaluation
The strength of the experiment is that use of apparatus. An electronic balance that shows 4 decimal places is used to measure the mass of the lighter. It improves the accuracy of the data, the mass of the lighter since it can show even a little change in mass. Also, the percentage error of the experimental value is 11.46%. The experimental value wasn’t perfectly accurate, but it still shows the result is highly precise. …show more content…

First, possible error is the lighter wasn't completely dried when its mass is measured after it is taken out from the water. As the lighter produce gas bubbles in the water, the water might have entered into it so this may have led the increase in mass. This can cause the value of the mass of gas released higher which makes the molar mass to change. To overcome this limitation, the lighter should be measured few minutes after it is taken out from the water to give some time to dry

In this lab there were five different stations. For the first station we had to determine an unknown mass and the percent difference. To find the unknown mass we set up the equation Fleft*dleft = Fright*dright. We then substituted in the values (26.05 N * 41cm = 34cm * x N) and solved for Fright to get (320.5g). To determine the percent difference we used the formula Abs[((Value 1 - Value 2) / average of 1 & 2) * 100], substituted the values (Abs[((320.5 - 315.8) /

The cylinder was adjusted to the water level because that kept the pressure on the tube and the water inside at a constant rate throughout the tube. If the graduated cylinder had not been adjusted, the test would have been introduced to a random error because it would have been a flaw that was always present and would affect the measurements of the experiment. When the unknown anti-acid was tested the first time, the results yielded a 40.2% yield of CO2. The second trial of part B was not as accurate due to using a mass of the unknown-acid that was too small for accurate results. The lack of accuracy came from a lack of precision which resulted in a human error because the amount that was broken off and selected for the trial was too small.

The experimental molar mass was calculated to be 87.5005 grams. Some source of error could be that there was not enough time to let the solution warm up to room temperature, letting the solid formed in the 11 dram dial to melt, causing the temperature probe to possibly read incorrectly. Also, while using a plastic pipet, the drops added were not consistent and varied in size. This could have led to different masses between the first and second set of 20 glycerol drops used in trial 2 and 3 of the experiment. These mistakes and errors can account for the percent error of 4.98%.

The hypothesis made, the density calculated in the experiment will stay the same because the density of the unidentified object will never change, was supported. The results support the hypothesis because in every trial the density always came out to 9g/mL. In trial one the mass was 71.16g, the volume was 8mL, and the density was 8.895g/mL, but when rounded to the proper sig fig came out to 9g/mL. In trial two the mass was 71.12g, the volume was 8mL, and the density was 8.89g/mL, but when rounded to the proper sig fig came out to 9g/mL. In trial three the mass was 71.14g, the volume was 8mL, and the density was 8.8925g/mL, but when rounded to the proper sig fig came out to 9g/mL. When averaged the mass was 71.14g, the volume was 8mL, and the density was 9g/mL. Errors that could have occurred are, not calculating the density correctly, not completely submerging the unidentified object with water in the graduated cylinder to get the volume, not rounding the sig figs correctly when finding the density, not measuring the unidentified object’s mass in grams, not measuring the unidentified object’s volume in milliliters, and not writing the correct units with the proper number or not the correct unit at all.

The mass percentage of unknown carbonate was 57.58%, this was ±0.98% more than the calculated percent mass of sodium carbonate. There was more metal carbonate in my sample than predicted in my brain. This calculation means that I discovered sodium carbonate. I didn’t predict so many students would discover potassium carbonate. We all had different amounts of the unknown carbonate between 1.0g ±0.1g-3.0g±0.1g. The slope of the graph is positive except for a few outliers.

A possible error could have occurred while measuring the mass of the individual pennies, while the pennies were dry and were allowed be measured individually, we did not clean or thoroughly examine each penny for flaws or cleanliness. This may have slightly affected the mass of the penny. Another possible source of error could have been measuring the volume of the water and the pennies in the water. Since we were using a measurement device the was accurate only to whole numbers, we had to make an educated estimate between the values provided by our measuring device. While these measurements are very close to the actual value a more accurate measuring device would have given more significant figures.

This type of lab heavily utilizes the concepts of stoichiometry. Stoichiometry looks into the relationship between the relative amounts of substances that are part of a reaction. You can also use stoichiometry for unit conversions, in this case, moles. Moles are a vital unit of measurement that is used to calculate and compare large quantities of small things. Chemists use moles rather than mass when determining relationships between multiple substances because they work with extremely small particles, so using the mass wouldn’t be productive.

The experimental values of experiment 1 and 2 was 64.6%. This is quite a large value because we likely made multiple human and experimental errors. Most of the errors probably occurred in experiment two because it had the largest value for the coefficient of friction. The percent value of experiment 1 and 2 was 34.2%, which is a medium value. Human and experimental errors in experiment three likely resulted in a greater coefficient of friction value, but the percent difference is not as drastic as the percent difference for experiments 1 versus 2.

After being heated for 30 minutes it weighed only 2.4g. Our group’s goal was to find out the correct formula. So we used stoichiometry in order to find the theoretical yield for each equation. Then all we had to do was compare which theoretical yield would have the closest mass to the actual yield to find the correct formula. Our 2nd equation came closest to weighing the same amount of the actual yield. It weighed in at 2.5g while the actual was 2.4g.
