What is the maximum mass of H2O that can be produced by combining 90.8 g of each reactant

  • chemistry -

    Write the equation and balance it.
    mols H2 = grams/molar mass
    mols O2 = grams/molar mass

    Convert mols H2 to mols product.
    Do the same for O2.
    The smaller number of mols wins; that will be the mols H2O produced. Then mol x molar mass H2O = grams H2O.
