Problem on Chemical Energetics.

Calculate the amount of heat liberated when 500 cm3 of N/10 (0.1 N) H2SO4 reacts with 400 cm3 of N/15 NaOH.

First you have to calculate how much hydroxide and sulfuric acid will really react. Calculate the chemical equation adn the amount and which will be left.
Then check in a table book the neutralisation heat for that reaction.

Thank you Hunter2. But I do not know how to find the number of moles when given the normality of the two substances.

What does normality mean? What other unit it has?
