How to calculate the heat evolved of ch3oh burns

Reference no: EM13531655

Methanol, CH3OH, is an efficient fuel with a high octane rating. Combustion of methanol occurs by the reaction:

CH3OH (g) + 3/2 O2 (g) ----> CO2 (g) +2H2O (l) delta H = -76.2 kJ/mol

Calculate the heat evolved when 85.0 g of CH3OH (g) burns (assume excess O2 (g)) and calculate the mass (#grams) of O2 (g) consumed when 500 kJ of heat is produced by this reaction.
