A cube of osmium metal 1.500 cm on a side has a mass of 76.31 g at 25? c. part a what is its density in g/cm3 at this temperature?

The volume of the cube osmium metal is calculated by multiplying the given dimension to itself three times.

v = (1.5 cm) (1.5 cm) (1.5 cm)

v = 3.375 cm³

Density is calculated by dividing the mass by volume.

d = (76.31 g) / (3.375 cm³)

d = 22.61 g/cm³

Thus, the density of the metal is approximately 22.51 g/cm³.
