WebJul 2, 2015 · You can't weigh something to the desired molarity. You can measure a mass, weigh a force, and calculate a concentration (molarity). Also if you start with the desired concentration, and then add acid/base to adjust the pH, then you are diluting the buffer and end up at a much lower concentration than intended. – Martin - マーチン ♦ WebMolarity is defined as the number of moles of solute in exactly 1 liter (1 L) of the solution: M = mol solute L solution M = mol solute L solution. ...
