2C2H6 + 7O2 ==> 4CO2 + 6H2O
mols C2H6 = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols C2H6 to mols CO2. That is
?mols C2H6 x (7 mols O2/2 mols C2H6) = ? = ?
Now convert mols CO2 to grams. g CO2 = mols CO2 x molar mass CO2 = ?
calculate the weight of co2 by complete combustion of 1.5 \g of ethane
