I have a solution made up of 100 ml of distilled water and 2.0g of NaOH. I need to determine the total volumeof the solution in order to the calculate the mass of the reaction mixture. How do I do this? We are to assume the density of the solution is the same as pure water, 1.0g/ml. Thanks.

    Since the post says "100 mL of solution" I assume that means the total volume is 100 mL and that the volume of the water is slightly less than 100 mL. The molarity = moles/L
    moles = 2/40 = 0.05
    0.05/0.1 = 0.5 M.
