A piece of metal has a mass of 85cg and a volume of 450L. What is its density in g/cm3? What would be the mass of 300 cm3 of this metal? What would be the volume of 00 ounces of this metal?

• physics -

m = 85 kg?
V = 450 L.

V = 450L * 1000cm^3/L = 450,000cm^3

D = 85,000g/450,000cm^3 = 0.189 g/cm^3.

Mass = 300cm^3 * 0.189g/cm^3 = 56.67 g =
0.0567 kg.
