WebCalculate the mass ratio of CH 4 to O 2 required for complete combustion. Solution: This is just the ratio of the molar mass of CH 4 (16 g) to that of two moles of dioxygen (2 x 32 g) Thus (64 g) / (16 g) = 4/1 = 4.0. Complete combustion of each kg of methane consumes 4 kg of dioxygen, which is supplied by the air. flowers nenaghWebFor a cell batch-reaction calculation, the identification number (cell number) is specified, and any reactants with that identification number are brought together and reacted.
