Question

What is the molar concentration (M= molarity) of a solution prepared by dissolving 50 g of NaCl in 750ml of water?
To be technical about it, the molarity can't be calculated. The definition of molarity is moles/L of <b>SOLUTION</b>. Placing NaCl in 750 mL water will NOT produce 750 mL of solution; the final solution will be greater than 750 mL.
I will assume the author of the problem MEANT to write soln instead of water.
mol NaCl = grams/molar mass
Then M = moles/L soln (0.750 L)
