  1. Sep 13, 2012 #1
    1. The problem statement, all variables and given/known data
    On boiling 1litre N/5 HCl, the volume of the aqueous solution decreases to 250mL. If 3.65g of HCl is removed from the solution then the concentration of resulting solution becomes?

    2. Relevant equations
    No idea, from where should i start

    1. Molarity of HCl?

    2. Moles of HCl removed?

    3. New volume?

    You will have moles of HCl left in solution, new volume after boiling, so you can find out new molarity, and by extension, new Normality.
