Density Worksheet
Mr. Vorstadt
Use the formula for density and volume to help answer the question below and your
knowledge of science.
V=LxWxH
Density has units of g/ cm3 for solids and g/mL for liquids
1. Define mass? ________________________________________________________________
______________________________________________________________________________
2. Define volume? ______________________________________________________________
______________________________________________________________________________
3. Define density? ______________________________________________________________
______________________________________________________________________________
Calculate the densities of the following objects. Remember to place units after each number.
4. Object A length = 6cm width = 3cm height = 1cm
mass = 36g
volume = _____ density = _____
5. Object B length = 10cm width = 5cm height = 2cm
mass = 300g
volume = _____ density = _____
6. Object C Use the water displacement method to determine the density of object C (silly putty).
initial water level in graduated cylinder = 25ml final water level after placing silly
putty into graduated cylinder = 29ml mass of silly putty=8g
volume = _____ density = _____
7. A gold-colored ring has a mass of 18.9 grams and a volume of 1.12 mL. Is the ring pure gold?
(The density of gold is 19.3 g/mL.)
8. Circle the materials that will float on water (density 1 g/ml)?
corn oil = 0.93 g/cm3
wood = 0.85 g/cm3
3
glycerine = 1.26 g/cm
steel = 7.81 g/cm3
3
corn syrup = 1.38 g/cm
rubber = 1.34 g/cm3
ice = 0.92 g/cm3
water = 1.00 g/cm3
9. Assuming the materials don’t mix, show how the materials would "stack up" in the beaker
below. Place the name of the material in the beaker according its density.
_____ 10. What is the density of a rock, which has a mass of 35 grams and a volume of 7.0 cm3?
A) 28 g/cm3
B) 42 g/cm3
C) 5 g/cm3
D) 0.20 g/cm3
_____ 11. An empty 250 mL beaker has a mass of 60 g. When 100 mL’s of oil is added to the
beaker, the total mass is 140 g. What is the density of the oil?
A) 1.4 g/ml
B) 0.8 g/ml
C) 0.6 g/ml
D) 1.7 g/m3
_____ 12. A substance is cut into several pieces. As compared to the density of the original
sample, the density of each piece will be
A) Greater
B) Less
C) The Same
13. Pumice is volcanic rock that contains many trapped air bubbles. A 225 gram sample
occupied 236.6 mL. What is the density of pumice?
Will pumice float on water? (The density of water is 1.0 g/mL.) Circle one YES or NO
14. A sample of lead is found to have a mass of 32.6 g. A graduated cylinder contains 2.8 mL of
water. After the lead sample is added to the cylinder the water level reads 5.7 mL. Calculate
the density of the lead sample.
