What two types of measurements are needed to calculate DENSITY?

• Mass and Volume

• Temperature and Mass

• Grams and Centimeters

• Volume and Weight

Answer explanation

Density = Mass / Volume

The density of water is 1.0 g / mL. What is the mass of 15 mL of water?

• 0.15 g / mL

• 15 g

• 15 mL

• 5 g

Answer explanation

D = 1.0 g/ml

v = 15 ml

find mass

m = D x v

m = 1.0 g/ml x 15 ml

ml units cancel out

m = 15 g
