The tank with a capacity of 0.2m³ contains oil weighing 160kg. What is the density of oil?

According to the conditions of the problem:

V = 0.2 m ^ 3 – the volume occupied by oil;

m = 160 kg is the mass of oil;

It is necessary to find the density of the oil p.

Density is defined as the ratio of the mass of a substance to the volume occupied by this mass:

p = m / V = 160 / 0.2 = 800 kg / m ^ 3.

Answer: the density of oil is 800 kg / m ^ 3.
