Measuring Volume and Mass Practice

A key made from an unknown metal has a density of 6.2 g/cm³ and a mass of 3.1 grams. What is the volume of the key, and could it be made of brass (density: 8.4 g/cm³), aluminum (density: 2.7 g/cm³), or neither?

• 0.5 cm³

  The key is made of brass.

• 0.5 cm³

  The key is made of neither brass nor aluminum.

• 2.0 cm³

  The key is made of aluminum.

• 2.0 cm³

  The key is made of neither brass nor aluminum.

• 19.22 cm³

  The key is made of neither brass nor aluminum.

Density is...

• a measure of how much matter is present in a substance.

• a measure of the space that matter occupies.

• the amount of matter in a given space or volume.

What is/are the metric unit/s for volume?

• Grams (g)

• Cubic Centimeters (cm³)

• Milliliters (mL)

• Grams per Cubic Centimeter (g/cm³)

• Grams per Milliliter (g/cm³)

What is the formula for volume, when density and mass are known?

• V=m/d

• d=m/V

• m=dV

• V=d/m
