What is the mass of 25 mL of a liquid if its density is 1.25 g/mL?
To calculate the mass of the liquid, we have to use this formula:
- Usually, density will have units of
The mass has units of grams,
The volume will have units of
We are given the density and volume, both of which have good units so all we have to do is rearrange the equation to solve for the mass:
Thus, the liquid has a mass of 31g.
