# How many milliliters of liquid will it take to mass out a quantity of 235 grams if the liquid has a density of 1.5g/ml

Hello!

By definition, density of a substance is its mass divided by its volume:

`rho=m/V.`

For a specific substance, density remains the same for any `m` (`V` is changing accordingly).

We can use this equation in any direction. For the known density and mass we can find the volume,

`V=m/rho.`

Here `V=(235g)/(1.5(g)/(ml)) approx 156.67 ml.`

This is the answer.
