How many times is the volume occupied by mercury less than the volume of oil of the same mass?
| March 2, 2021 | education
The volume occupied by mercury:
V1 = m1 / ρ1, where m1 is the mass of mercury, ρ1 is the density of mercury (ρ1 = 13600 kg / m³).
Oil volume:
V2 = m2 / ρ2, where m2 is oil mass, ρ2 is oil density (ρ1 = 800 kg / m³).
According to the conditions of the problem: m1 = m2.
V2 / V1 = (m2 / ρ2) / (m1 / ρ1) = ρ1 / ρ2 = 13600/800 = 17 p.
Answer: The volume occupied by mercury is 17 times less than the volume occupied by oil.
