Heat??? Please HELP!!!

Question

One of the reactions used in some hand-warmer packets is the oxidation of iron to form rust. The formation of 1 mole of rust produces approximately 410kJ of heat.

a. If this heat were absorbed by 200.0g of water at 22.0 degrees celcius in a calorimeter, how hot could the water be made?

b. If only 0.10 mole of rust were formed, how hot could 200.0g of water at 22 degrees celcius become.

Please Explain...
