thecandydoll:
I have a doubt in practical paper June 2008 32.
Q1..it says to calculate enthalpy of reaction.
HOW?
i know its mcdeltat
but masss of what?

thecandydoll:
Yes thank you very much for your answerrs =(

nid404:
sorry i guess im late. You use the mass of the solution.

Basically density of the solution would be 1g/cm3  so 1g=1cm3  So you see the volume of the liquid used...that's the mass ;)

Ykov:
Please Note: If they give you mass of the solid, ignore it completely please and just use the mass of the solution
