Question

A cube made of osmium, the elemnt with the highest density,measures 5centimeters along each edge and has a mass of 2825 grams .what is the density ,in grams per cubic centimeters of the osmium from which the cube is made ?(density is mass per unit volume)

Answer 1

Volume = length x width x depth, so the volume of the cube is 5 x 5 x 5 = 125 cm^3

 

Density = mass/vol

 

D = 2825g/125cm^3 = 22.60g/cm^3
