Initial data: V (volume that the liquid takes) = 125 l; m (liquid mass) = 100 kg.
SI system: V = 125 l = 125 dm ^ 3 = 125 * 10 ^ -3 m ^ 3 = 0.125 m ^ 3.
Let’s calculate the density of the liquid by dividing its mass by the occupied volume: ρ = m / V = 100 / 0.125 = 800 kg / m ^ 3.
Three liquids can correspond to this density value: kerosene, oil, alcohol.
Answer: The density of the liquid is 800 kg / m ^ 3.
