Se sigue los siguientes pasos:
m○ = 5 g = ρ(métal).V
m○ - ρ(agua).V = m1 = 3 g ↔ ρ(agua).V = m○-m1
m○ - ρ(aceite).V = m2 = 3,24 g ↔ ρ(aceite).V = m○-m2)
Se procede a reemplazar datos:
d(metal) ≈ ρ(métal)/ρ(agua) = m○/(m○-m1) = 5/(5-3) = 2,5
d(aceite) ≈ ρ(aceite)/ρ(agua) = (m○-m2)/(m○-m1) = (5-3,24)/(5-3) = 0,88
