Methanol burns in oxygen to make carbon dioxide and water. The equation is exothermic, with 1452kJ/mol. of energy being released.
2CH3OH + 3O2 = 2CO2 + 4H2O
-molar mass of methanol=32g/mol. Use the value to calculate the energy release when 4g of methanol is burned.
1452 kJ for 2 mol or 2 x 32 = 64 g.
1452 kJ x 4/64 = ??
