Problem 1: For the reaction 2CH3OH(l) +3O2(g) = 2CO2 +4H2O(l) I calculated that the change in molarentropy of the system is 313.7Joules/(moles*kelvin). The question then asked what is the entropychange of the system when 2.35 moles ofO2 react. I multiplied 313.7 Joules/(moles*kelvin) by2.35 moles of O2 and also divided by 3 moles ofO2 because of the \"3\" coefficient, and got 246Joules/kelvin and I just want to make sure that last part wascorrect. Specifically, was I correct to both multiply by 2.35 anddivide by 3.
Problem 2: Very similar problem. For the reactionH2(g) + F2(g) = 2HF(g) Icalculated that the change in molar entropy of thesurroundings is 1,819 Joules/(moles*kelvin). Thequestion then asked to calculate the entropy change of thesurroundings when 2.15 moles of H2(g)react, so I multiplied 1,819 Joules/(moles*kelvin) by 2.15 moles ofH2(g) and then divided by 1 moles ofH2(g) since the coefficient is \"1\" and got 3,911Joules/kelvin, and I just want to make sure this last part iscorrect. Specifically, was I correct to multiply by 2.15 and thendivide by 1
