The mass is realy the amount of solute in the solution. If it is known for a given volume solution, the conc. of the solution can be found.

It all depends on the concentration you're trying to find. Sometimes, if the mass of the solute is too large, the mass of the solution is important. The usual assumption is that the mass of the solute is << (much less than) the mass of the solvent, so that the mass of the solvent is essentially the same as the solution. This is not always the case.

As the mass of the solution increases, the concentration will decrease. The reverse will happen if you decrease the mass of the solution.
If you think of making a glass of cordial. In one cup of water, 20mls of cordial could be tasted however that same 20ml of cordial might might not be detectable by you in 100 litres of water.

units of concentration is mol/L
n mass is needed bcuz no. of mols = mass/molar mass
=m/(g.mol)
n this shud ans ur que..
if not reply me bak
