We are asked what mass of natural gas (CH4) must you burn to emit 268 kJ of heat.
We'll use the thermochemical equation to calculate the mass of CH4.
Molar mass CH4 = 16.05 g/mol
What mass of natural gas (CH4) must you burn to emit 268 kJ of heat?
CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g) Hrxno= –802.3 kJ/mol
