Question

If 89.2 mL of a liquid has a mass of 75.2 g, how would you calculate the liquid's density?

Answer 1

`0.843 g/(mL)`

Explanation:

To calculate the density, we have to use the formula below:

`"Density = (Mass)/(Volume)`

• Usually, density will have units of `g/(mL)` when dealing with a liquid or units of `g/(cm^3)` when dealing with a solid.

• The mass has units of grams, `g`.

• The volume can have units of `mL` or `cm^3`

We are given the mass and the volume, both of which have good units. All we have to do is plug the given values into the equation:

`Density =(75.2 g)/(89.2mL)`

Thus, the liquid has a density of 0.843 g/mL.
