SUMMARY
The molar mass of substance A, derived from the reaction 2 A + 3 B + 1000 kJ ==> 4 C, is calculated to be 23.7 g/mol. Given 35.5 g of A and 750 kJ of heat released, the heat per mole of A is determined to be 500 kJ/mole. The number of moles of A used in the reaction is 1.5, leading to the final molar mass calculation. The discussion highlights a potential ambiguity in the problem statement regarding the sufficiency of heat for complete reaction.
