# How do we measure liquid mass?

Feb 5, 2017

Are you asking how one can measure the mass of a liquid?

#### Explanation:

Apart from directly measuring the mass; i.e. adding the liquid to a tared container sitting on a balance, a measured volume could be delivered if we know the density of the liquid.

$\rho , \text{density"="Mass"/"Volume}$, and thus $\text{mass"="volume} \times \rho$.

If we deliver a solution of known concentration, then it is simply a matter of taking the appropriate volume that contains the required stoichiometric equivalent.

$\text{Concentration"="Moles"/"Volume}$,

thus $\text{moles"="concentration"xx"volume}$.
