Question

how much heat is produced by the complete combustion of 205g of CH4

Answer 1

Molar mass of methane, CH4 = 16.04 g/mol

205g/ [16.04g/mol] = 12.78 moles of CH4

Each mole of gas produces -802 kJ of heat when mixed with O2

-802 kJ/ mol * 12.78 mol = -10,250 kJ of heat

Answer 2

thank you!
