# For the reaction #CH_4 + 2O_2 -> CO_2 + H_2O#, how many moles of carbon dioxide are produced from the combustion of 100g of methane?

The moles of carbon dioxide produced from 100 g methane is 6 moles.

Balanced Equation

Multiply the given mass by the inverse of its molar mass.

Now multiply the moles methane by the mole ratio between methane and carbon dioxide so that methane is canceled.
