A copper pan has a mass of 0.5 kg if a pan of the same dimensions is made of steel as it will have a mass.

Initial data: m1 (mass of a copper pan) = 0.5 kg.

Reference data: ρ1 (copper density) = 8900 kg / m ^ 3; ρ2 (density of steel) = 7800 kg / m ^ 3.

Since both the copper and steel pan have the same dimensions (V1 = V2), the mass of the steel pan can be determined from the equality: m1 / ρ1 = m2 / ρ2, whence m2 = m1 * ρ2 / ρ1.

Let’s calculate: m2 = 0.5 * 7800/8900 = 0.438 kg.

Answer: The weight of a steel pan will be 0.438 kg.
