The combustion of propane and oxygen produces carbon dioxide and water. What mass of water is produced from the combustion of 10.4g of propane, C3H8

1 answer

C3H8 + 5O2 ==> 3CO2 + 4H2O
mols C3H8 = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols C3H8 to mols H2O
Now convert mols H2O to g H2O. g = mols x molar mass.
