A piece of metal with a volume of 50 cm3 has a mass of 355g what is the density of the metal what kind of metal is it?

Initial data: V (volume of a metal bar) = 50 cm ^ 3; m (mass of a metal bar) = 355 g.

Reference data: V = 50 cm ^ 3 = 50 * 10 ^ -6 m ^ 3; m = 355 g = 0.355 kg.

The density of the metal is determined by the formula: ρ = m / V.

Let’s calculate: ρ = 0.355 / (50 * 10 ^ -6) = 7100 kg / m ^ 3.

From the density table of solids, it can be determined that the density of 7100 kg / m ^ 3 corresponds to zinc.

Answer: According to the calculation, the density of the metal is 7100 kg / m ^ 3 (zinc).
