m = 100 kilograms is the mass of the liquid;
V = 125 liters – the volume of the liquid.
It is required to determine the density of the liquid ro (kg / m ^ 3).
First, we bring the units of volume to the SI standard cubic meter:
V = 125 liters = 125 dm ^ 3 = 0.125 m ^ 3.
Then the density of the liquid is equal to:
ro = m / V = 100 / 0.125 = 800 kg / m ^ 3.
Answer: the density of the liquid is 800 kilograms per cubic meter.
