Answer: Density Calculations

Mercury (Hg) has a density of 13.6 g/cm3. What is the mass of 95 mL of Hg in grams? In pounds?

Density = mass (g)

volume (cm3)

Step 1: 95 mL × (1 cm3/1 mL) = 95 cm3

Step 2: 13.6 g/cm3 = x/95 cm3

x = 1.29 × 103 g but report 1.3 × 103 g

Step 3: 1.3 × 103 g × (1 lb/454 g) = 2.9 lbs
