Problem 1: For the reaction 2CH3OH(l) + 3O2(g) = 2CO2 + 4H2O(l) I calculated that the change in molar entropy of the system is 313.7 Joules/(moles*kelvin). The question then asked what is the entropy change of the system when 2.35 moles of O2 react. I multiplied 313.7 Joules/(moles*kelvin) by 2.35 moles of O2 and also divided by 3 moles of O2 because of the "3" coefficient, and got 246 Joules/kelvin and I just want to make sure that last part...
