Question

When methanol, CH3OH, is burned in the presence of oxygen, a large amount of heat is released. Based on the balanced thermochemical reaction, how much heat is released, in units of kJ, when 22.3 g of methanol reacts with 60.4 g of oxygen? CH3OH(g) + 3/2 O2(g) ? CO2(g) + 2 H2O(l) ?rH = -764 kJ/mol

Step 1

Molar mass of CH3OH = 32 g/mol Molar mass of O2 = 32 g/mol Moles of CH3OH = 22.3 g / 32 g/mol = 0.697 moles Moles of O2 = 60.4 g / 32 g/mol = 1.888 moles Show more…
