Initial data: V (tank capacity) = 20 m ^ 3; m (mass of oil in the tank) = 16000 kg.
The density of oil can be determined by dividing the mass of oil in a tank by the volume of that tank:
ρ = m / V.
Let’s perform the calculation:
ρ = 16000/20 = 800 kg / m ^ 3 (corresponds to the table density value).
Answer: According to the calculation, the density of oil is 800 kg / m ^ 3.
