Question

If a sample of iron with a density of 7.80 g/cm3 displaces 75.0 mL of water when placed in a beaker, what is its mass?

Answer 1

If a sample of iron with a density of 7.80 g/cm^3 displaces 75.0 mL of water when placed in a beaker, its mass is 585 g.

Answer 2

1 mL = 1 cm³

75.0 mL = 75.0 cm³

Density = mass / volume

7.80 = mass / 75.0

mass = 7.80 x 75.0

mass = 585 g

hope this helps!
