Question

A cube of zinc and a cube of silver have the same volume. The mass of the zinc is 55lbs (pounds). What is the mass of the silver in kg (kilograms)?

Answer 1

Answer:

Explanation:

Convert 55lbs to kg

(55 lb)*(453.6 g/lb) = 24948 g or 249.48 kg

Density of zinc = 7140 kg/m^3

Find the volume occupied by 249.48 kg:

  (249.48 kg)/(7140 kg/m^3) = 0.055 m^3

Density of silver = 10,490 kg/m^3

Mass of Ag in 0.055m^3:

  (0.055m^3)*(10,490 kg/m^3) = 577 kg
