Calculate the mass of water produced when 9.53

g
of butane reacts with excess oxygen

1 answer

2C4H10 + 13O2 ==> 8CO2 + 10H2O

mols C4H10 = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols C4H10 to mols H2O.
Now convert mols H2O to grams H2O with g = mols x molar mass = ?
