Calculations

Part I: Density of Unknown Liquid
Calculate the mass of the liquid for each trial. (Subtract the mass of the empty graduated cylinder from the mass of the graduated cylinder with liquid.)
Trial 1
36.4-25.6= 10.8
The mass of the unknown liquid from Trial 1 is 10.8 grams
Trial 2
36.5-25.8= 10.7
The mass of the unknown liquid from Trial 2 is 10.7 grams
Trial 3
36.3-25.4=10.9
The mass of the unknown liquid from Trial 3 is 10.9
Calculate the density of the unknown liquid for each trial. (Divide the mass of...
