33.01 g CO2
27.04 g H2O
mols CO2 = 33.01/44 = ? = mols C.
mols H2O = 27.04/18 = ? and that x 2 = mols H.
Now find the ratio of C to H with C being no larger than 1.0
27.04 g H2O
mols CO2 = 33.01/44 = ? = mols C.
mols H2O = 27.04/18 = ? and that x 2 = mols H.
Now find the ratio of C to H with C being no larger than 1.0
