PSSA Review #12 (Density and Thermal Energy)

A bone has a mass of 93.5 grams and a volume of 50.0 cubic centimeters. Calculate its density.

• 93.5 grams divided by 50.0 cubic centimeters equals 1.87 grams/cubic centimeter

• 93.5 grams times by 50.0 cubic centimeters equals 4,675 square cubic centimeters

• 50 cubic centimeters divided by 93.5 grams equals 0.53 cubic centimeters/gram

• 50 cubic centimeters times 93.5 grams equals 4,675 square grams

A glass vase has a volume of 2,200 cubic centimeters and a mass of 550 grams. Calculate its density.

• 550 grams divided by 2,200 cubic centimeters equals 0.25 grams/cubic centimeter

• 550 grams times by 2,200 cubic centimeters equals 0.25 square cubic centimeters

• 2,200 cubic centimeters divided by 550 grams equals 4 cubic centimeters/gram

• 2,200 cubic centimeters times 550 grams equals 1,210,000 square grams

A glass windowpane has a volume of 0.15 cubic meters and a mass of 42 kilograms. Calculate its density.

• 42 kilograms divided by 0.15 cubic meters equals 280 kilograms/cubic meter

• 42 kilograms times by 0.15 cubic meters equals 280 square cubic meters

• 0.15 cubic meters divided by 42 kilograms equals 0.003 cubic meters/kilogram

• 0.15 cubic meters times 42 kilograms equals 6.3 square kilograms

Milk in a bottle has a density of 1.04 grams per cubic centimeter and a volume of 775 cubic centimeters. Calculate its mass.

• 1.04 grams per cubic centimeters times 775 cubic centimeters equals 806 grams

• 1.04 grams times by 775 cubic centimeters equals 806 square cubic centimeters

• 775 cubic centimeters divided by 1.04 grams equals 745.19 cubic centimeters/gram

• 775 cubic centimeters times 1.04 grams equals 806 square grams

A block of marble has a volume of 0.25 cubic meters and a density of 260 kilograms per cubic meter. Calculate its mass

• 260 kilograms times 0.25 cubic meters equals 65 kilograms

• 93.5 grams times by 50.0 cubic centimeters equals 4,675 square cubic centimeters

• 50 cubic centimeters divided by 93.5 grams equals 0.53 cubic centimeters/gram

• 50 cubic centimeters times 93.5 grams equals 4,675 square grams

A potato has a density of 0.52 grams per cubic centimeter and a mass of 130 grams. Calculate its volume.

• 130 grams divided by 0.52 grams per cubic centimeter equals 250 cubic centimeters

• 0.52 grams times by 130 cubic centimeters equals 67.6 square cubic centimeters

• 0.52 cubic centimeters divided by 130 grams equals 0.004 cubic centimeters/gram

• 0.52 cubic centimeters times 130 grams equals 67.6 square grams

A marble statue has a mass of 91 kilograms and a density of 260 kilograms per cubic meter. Calculate its volume.

• 91 kilograms divided by 260 kilograms per cubic meter equals 0.35 cubic meters

• 91 kilograms times by 260 cubic meters equals 23,660 square cubic meters

• 260 kilograms per cubic meter divided by 91 kilograms equals 2.85 cubic meters/kilogram

• 260 kilograms per cubic meter times 91 kilograms equals 23,660 square grams
