Explanation:
This looks like a limiting reactant problem.
We are given the masses of two reactants and asked to determine if we have enough to make a given amount of product.
1. Assemble the information
We will need a balanced equation with masses and molar masses, so let’s gather all the information in one place.
M_r: 2.016 32.00 18.02
2H₂ + O₂ ⟶ 2H₂O
Mass/g: 2.56 20.32
2. Calculate the moles of each reactant
3. Calculate the moles of H₂O from each reactant
4. Calculate the mass of H₂O
