2C2H6 + 7O2 => 4CO2 + 6H2O
This is a limiting reagent problem; you know that because amounts are given for BOTH reactants. Therefore, you must identify the limiting reagent.
How much H2O can be produced by 0.1 mol C2H6. That is
0.1 mols C2H6 x (6 mols H2O/2 mols C2H6) = ?
How much H2O can be produced by 0.1 mol O2? That is
01 mol O2 x (6 mols H2O/7 mols O2) = ?
The mols of water will be the SMALLER of the two.
Then convert to grams. grams = mols H2O x molar mass H2O = ?
What mass of water is produced when 0.1 moles of C2H6 is reacted with 0.1 moles of
O2?
