Calculate the mass of water produced from the reaction of 24.0 g of H2 and

160.0 g of O2. What is the limiting reagent?

1 answer

Write the equation and balance it.
Convert what you have in grams to mols.
Convert mols of each reactant to mols of the product. Take the smaller number, which is the limiting reagent. Then convert mols of that reagent to grams water.
