How much heat (in  kJ) is evolved in converting 1.00 mol of steam at 155.0 ^C to ice at -50.0^C? The heat capacity of steam is 2.01 J/g * C and of ice is 2.09 J/g * C.

I basically just need to know how to do the problem, the steps required so i can use it for future referece, if you give the answer than it will be help full too, so anyways...

Im most certain you have to use q= m x Cs x T for the equation and I have tried that, but i get a bit confused with the two Specific Heat Values, how would I apply them into the equation?

Thanks

You use in sequence.

How much energy to take steam from 155^oC to 100^oC etc etc.
