What is the molar concentration (M= molarity) of a solution prepared by dissolving 50 g of NaCl in 750ml of water?

  • Chemistry - ,

    To be technical about it, the molarity can't be calculated. The definition of molarity is moles/L of SOLUTION. 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)
