WebAug 29, 2024 · density = mass / volume. You can rewrite the equation to solve for mass: mass = volume x density. Density of liquids usually is expressed in units of g/ml. If you know the density of a liquid and the volume of the liquid, you can calculate its mass. Similarly, if you know the mass and volume of a liquid, you can calculate its density.
