Question

how many moles of Methane are required to produce 22 grams CO2 for combustion
hint: CH4+2O2 gives CO2+2H2O

Answer 1

By unitary method and stoichiometric calculation, CH4 + 2O2 → CO2 + 2H2O. 1 mol of methane → 1 mol of carbon dioxide (→ indicates “gives”) Hence 16 g of methane → 44g of carbon dioxide.
