By reading the new volume of the liquid substance amount one will then subtract the initial milliliter amount from the final volume reading, thus giving you the volume of the rock sample. Using the mass of the sample rock obtained one will then divide the final volume reading unveiling the density of the
# 1: Part B Explain in 2 or 3 sentences how the atomic weight is what is reported. Answer # 1: Atomic weight or atomic mass is basically the average mass of atoms of an element. Atomic mass is calculated by using the naturally occurring relative abundance of isotopes. Atomic weight determines the size of the atom.
The Controlled Variable for this experiment was mass and volume. When identifying an unidentified object finding the density is the easiest way to do it because, any pure substance has a specific density at a specific temperature and each element and compound has a unique density associated
In this week’s lab we had to determine the density of a quarter, penny, and dime. My question was “How does is each coin?” Density is the amount of mass in an object. To find the density of each coin in this lab, we used a triple beam balance to find each coin’s mass and a graduated cylinder to find their volumes. With all this information, I can now form a hypothesis.
The __average atomic mass__ of an element refers to the atomic masses of the isotopes of the element, taking into account the different abundances of the element’s isotopes. The average atomic mass can be calculated using the following
If we were given a random sample of pennies, then we could measure the mass and the volume of the pennies. From these measured values we could calculate the density. Then we could compare our calculated density to the given density value of copper and we could find the the percentage of error between copper and the measured density. Conclusion: If the percentage of error between the copper and the measured density of the pennies was large and the values were not in comparison to the density of copper, then we would know that the density of a penny is not the same as the density of pure copper.
Also, if a planet is smaller than not even the biggest moon
1. method via radar of measuring near star distances, Direct distance measurements are based upon the Astronomical unit (AU), which is the distance between the Earth and the Sun. Historically, observations of transits of Venus were crucial in determining the AU; in the first half of the 20th century, observations of asteroids were also important. Presently the orbit of Earth is determined with high precision using radar measurements of distances to Venus and other nearby planets and asteroids,[1] and by tracking interplanetary spacecraft in their orbits around the Sun through the Solar System. Kepler's Laws provide precise ratios of the sizes of the orbits of objects orbiting the Sun, but provides no measurement of the overall scale of the orbit system. Radar is used to measure the distance between the orbits of the Earth and of a second body.
One of the reasons Pluto isn’t a planet is because of its size. If Pluto isn’t a planet then Jupiter shouldn’t be a planet. This proves that planets shouldn’t be based on a size. Based on my logic, Pluto orbits the sun. If it wasn’t a planet it wouldn’t orbit the sun because all the other planets orbit the sun and Pluto does.
According to Dr. Stern the astronomers who made this decision felt “that decision was based in part upon the growing realization that Pluto is far from the only large object in the Kuiper Belt, the ring of icy bodies that orbits the sun beyond Neptune. The IAU came up with a new definition of "planet”, they said the definition
The development of the mass spectrometer allowed the mass of atoms to be measured with increased accuracy. The device uses a magnet to bend the trajectory of a beam of ions, and the amount of deflection is determined by the ratio of an atom's mass to its charge. The chemist Francis William Aston used this instrument to show that isotopes had different
Gravity formed and maintains our solar system because it helped formed the sun, helped form the planets, and keeps the planets in orbit around the sun. According to the “Formation of the Solar System” video on discoveryeducation.com, the sun was formed when a nebula collapsed die to gravity and as the matter condensed in the center, its temperature rose and nuclear reactions began forming our sun. This shows that gravity helped form our sun because it made a nebula collapse, and the collapsed nebula is what formed the sun. According to discoveryeducation.com, the planets formed when remanent dust and gas from the formation of the sun formed atoms, and molecules which became our planets. Once the planets were big, their own gravity pulled to

The mass of Venus is 4.867x10^24 kilograms and earth is slightly larger at 5.972x10^24 kilograms. The way to notice they are similar from these equations is they have the same amount of digits in the number. There densities are only 0.27g/cm^3 apart and once again earths density is greater. The density of earth is 5.51g/cm^3 and Venus’ is only 0.27g/cm^3 smaleer than Earths at
Why is Pluto considered a dwarf planet? People consider Pluto as the dwarf planet and that it is too small to be considered an actual planet. Pluto is the 9th planet away from the sun and it still orbits the sun but it takes 248 years which is a very long time. Being the 9th planet furthest from the sun this might also be a reason for why Pluto is considered a Dwarf planet due to the length and how hard it will be to see it from earth.
