mol of H2 is 2 grams
8.08/2 = 4.04 mols
so
4.04 mols of H2O produced
H2O = 2+16 = 18 grams per mol
18 * 4.04 = 72.7 grams
For the reaction 2H2 + 1O2 à 2H2O, there are 8.08 grams of H2 available.
2. Use the ratio of stoichiometric coefficients in the reaction above to determine how many moles of H2O can be produced from the H2 available.
Then, use molar mass to convert the moles of H2O into grams.
The answer I got is 324.36 grams
