Two students are doing the candle lab. They put 100g of water in the pop can. The starting temperature of the water was 24 degree C. The final
temperature is 34 degree C. The mass of the candle before burning was
25.0 g. The final mass of the candle was 24.2 g. The "c" (specific heat) of
water is 4.2 J/g degree C. The molar mass of wax is 352 g/mol. Remember
to convert J to KJ (1000 J = 1 KJ). Calculate the KJ/mol heat of
combustion of wax. They put the candle way too far away from the can :) *
