1. The problem statement, all variables and given/known data I'm supposed to find the heat of combustion for candle wax (which was used to boil water in a simple calorimeter), yet I have no clue on how to do it, the lab books at school do not tell anything about the calorimeter's specific heat or give a formula for heat of combustion. So far I have my final temperature at 42.0 degrees Celsius, mass of 97.00g (after melting, with base), 1850 cal/g degrees Celsius absorbed by the can (formula used was Cal=mass H2O X Temperature Change H2O X Specific Heat of Water). My mass of H2O was 50g (assuming 1 ml is 1g, unless I got that backwards and its 1mg, I never really understood a few parts of the lab). The mass of my wax is 0.20g (97.20g - 97.00g). 2. Relevant equations All I know is the candle wax's formula, C36H74 We aren't allowed to take the lab books home, and my data table is brief and straight to the point, the way my teacher wants it to be. I could figure it out on my own if I just get the formula, unless I forget something.
