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"ρ,density=MassVolume, and thus "mass"="volume"xxrhomass=volume×ρ.

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"Concentration=MolesVolume,

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