Name: ______________________________________ Hour: ____________ Calculating Density Density = Mass divided by Volume D=M/V Mass = Density times Volume M=DxV Volume = Mass divided by Density V=M/D - Show your work and Circle your answers & Include Labels - 1. 4 cm of a mystery substance has a mass of 3.2 grams. What is the density of the mystery substance? 2. A diamond with a volume of 2 cubic centimeters has a mass of 7 grams. What is its density? 3. The density of cork is 0.2 g per cm. If I have a cork with a mass of 0.4 grams, what would its volume be? 4. The density of steel is 7.8 g/cm. If you have a steel cube that has a volume of 10 cm, what is its mass? 5. If a loaf of bread has a volume of 2270 cm and a mass of 454 g. What is the density of the bread? 6. A liter (which is the same as 1,000 ml) of water has a mass of 1000 g. What is the density of water? ( HINT: 1 ml = 1 cm ) 7. A block of wood has a density of 0.6 g / cm and a volume of 1.2 cm. What is the mass of the block of wood? 8. Use the data below to determine the density of each substance. Then use the chart below to determine the identity of each substance. Substance Density Mass (g) Volume (cm ) 171 15 148 Density (g / cm ) Substance Gold 19.3 Mercury 13.5 Lead 11.4 Iron 7.87 Aluminum 3.7 Bone 1.7-2.0 Gasoline 0.66-0.69 Air (dry) 0.00119 40 475 250 680 1,000 9. You are given a golf ball that has a mass of 30 grams and a volume of 12 cubic centimeters, and a baseball that has a mass of 350 grams and a volume of 60 cubic centimeters. Calculate the density of each object to determine which one has the greater density. Will either sink if placed in a pan of water? 10. Your cell-phone has a mass of 800 g and a volume of 50 cm3. Calculate its density and compare it to the density of water to determine if it would sink/float if you dropped it in a pool. 11. Put the following three liquids in order of increasing mass: Liquid A has a density of 2.4 g/cm3 and a volume of 30 cm3. Liquid B has a density of 2.9 g/cm3 and a volume of 15.0 cm3. Liquid C has a density of 0.36 g/cm3 and a volume of 80 cm3. If you mixed these 3 liquids together what would happen? Density of Some Common Substances Substance Density (g/cm3) Air 0.0013 Feathers 0.0025 Wood(Oak) 0.6 - 0.9 Ice 0.92 Water 1.00 Bricks 1.84 Aluminum 2.70 Steel 7.80 Silver 10.50 Gold 19.30
