Stress-test concentration by changing solution volume and solute amount without changing your main result.

Molarity is the number of moles of solute per litre of total solution. Its standard unit is mol/L, also written as M.
Yes. Convert grams to moles by dividing the solute mass by its molar mass, then divide those moles by solution volume in litres.
Use the final total solution volume, not only the amount of solvent added.
