Divide the mass by the density of the substance to determine the volume (mass/density = volume). Remember to keep the units of measure consistent. For example, if the density is given in grams per cubic centimeter, then measure the mass in grams and give the volume in cubic centimeters. ...
Generally, the exact concentration of the analyte must be known to achieve accurate results. The concentrations are usually expressed in units of moles per liter (mol/L). After the titration has been carried out, the concentration of the titrant, information from the balanced chemical reaction bet...
