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, "density"="Mass"/"Volume"#, and thus #"mass"="volume"xxrho#.

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.

#"Concentration"="Moles"/"Volume"#,

thus #"moles"="concentration"xx"volume"#.
