The mass of 15 cm3 of some substance is 109.5 g.

Initial data: V (volume of some substance) = 15 cm ^ 3; m (mass of some substance) = 109.5 g.

SI system: V = 15 cm ^ 3 = 15 * 10 ^ -6 m ^ 3; m = 109.5 g = 0.1095 kg.

To determine the type of a certain substance, we calculate its density and compare it with the tabular values of the density of various substances: ρ = m / V = 0.1095 / (15 * 10 ^ -6) = 7300 kg / m ^ 3 (the resulting value corresponds to the density of tin) …

Answer: Some substance is tin.
