In this lab, we were trying to figure out the density of unknown metals. We determined the density at the end by first measuring the mass of the metal on a scale, then using water displacement, finding the volume of the metal. First, we decided to use metal B. We took out one piece of the metal and measured the mass by placing it on the scale. Then, we filled up the graduated cylinder with exactly 20 mL of water. After filling up the cylinder, we gently placed the metal inside and recorded the new volume of the water. Each time it was the same, 24.0mL. We then realized that the volume of metal B itself was 4.0mL. After doing the same process for each piece of metal B, we calculated the density by taking the starting mass of each metal, and
