Question

The density of osmium, which is the densest metal, is 22.57 g/cm³. What is the mass of a block of osmium that measures 1.00 cm x 4.00 cm x 2.50 cm? Show your work. Be aware of significant figures!

Answer 1

The mass of the osmium is 226 g.

V = lwh = 4.00 cm × 2.50 cm × 1.00 cm = 10.00 cm³

Mass = 10.00 cm³ × (22.57 g/1 cm³) = 226 g
