Question

Consider the reaction between acetylene, C2H2, and oxygen in a welding torch: If 5.4 moles of acetylene react with sufficient oxygen, how many grams of CO2 will be formed?
2C2H2 + 5O2 ==> 4CO2 + 2H2O

Using the coefficients in the balanced equation, convert mols C2H2 to mols CO2.
Then convert mols CO2 t5o grams; g CO2 = mols CO2 x molar mass CO2.
how do I figure this out
2C2H6+7O2-->4CO2+6H2O,
