Balance this equation
butane+O2 >> CO2 + H2O
Then, apply Hess' Law.
I will be happy to critique your thinking.

Thank you. there is also a second part.
B.) assuming that all the heat evolved in burning 30 g of butane is transferred to 8 kg of water at 22.2 degrees celsius (specific heat=4.184 J/gxK), calculate the final temperature of the water.
