Example 1: Molar mass of salt (NaCl) is 58.5 g/mol, so if you dissolve 58.5g of salt in enough water to make 1.00 liter of solution, you have one mole of solute dissolved per liter of solution. The concentration of this solution is one molar (1.00 mol/L or 1.00M)

Molarity - Quia
Molarity, M. Molarity is a means of representing a solution’s concentration. In other words, it expresses how much dissolved solute can be expected from a given volume of solution. The . molar concentration or molarity, M, of a solution is used to indicate the number of moles of solute per liter of solution:

Since they know the volume they started out with they can compute the molarity using the calculated mass. Mr. Green was the murderer. I had great results with this lab, even if their lab techniques weren't perfect since the given range for Mr. Green was 0.5 - 1.5M anyway.
