URGENT Question
« on: June 28, 2011, 06:11:03 AM »
*delete me* My exam is tomorrow and I don't quite understand how to solve this question:

Find the maximum number of moles of salt that can be formed when 20.0 cm3 of 0.200 M dilute sulfuric acid is allowed to react with 30.0 cm3 of 0.300 M sodium hydroxide.

I don't have the answer 'cos its a practice question, but can someone provide me with the working?

My question is: how to I convert volume to mass with the knowledge of the number of moles?

THANKS THANKS THANKS IN ADVANCE! :P

You have the concentration of the solution and the volume. That should give you number of moles.
Write down the chemical equation for the reaction between sulphuric acid and sodium hydroxide. From there it is just stoichiometry. Please don't hesitate to ask if you have any further doubts. :)

This is a limiting reagent problem. Reaction should be balanced!
