<u>Step 2: Identify Conversions</u>
Molar Mass of H - 1.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol

3.32963 mol H₂O ≈ 3.33 mol H₂O
Answer: A. 5.41
Explanation:
To calculate the moles :
According to stoichiometry :
3 moles of require = 2 moles of
Thus 0.0261 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 3 moles of give = 3 moles of
Thus 0.0261 moles of give =
of
Mass of
Thus 5.41 g of solid lead will be produced from the given masses of both reactants.
