1. The problem statement, all variables and given/known data A sample of sulfur, mass 2.56g, is burned in excess oxygen inside a calorimeter of heat capacity 923 J/K and insulated by 815g of water. If the sole product of combustion is SO2(g), what is the expected increase in temperature? 2. Relevant equations q = mcΔT q = CΔT 3. The attempt at a solution I am given that the ΔHof = -296.8 kJ/mol for SO2(g) and the enthalpy of formation of oxygen gas and sulfur is 0. S(s) + O2(g) → SO2(g) So, I did: (1g / 32.06 g/mol)(-296.8 kJ/mol) = - [(4.184 g/molK)(815g)ΔT + (923 J/K)(ΔT)] After isolating for ΔT and converting units to J, i found my answer as 2.136 K but this is incorrect. Any comments on where I went wrong? Thanks!
