    The theoretical yield of H2O is 1.63 grams

    Explanation:

    Step 1: Data given

    Mass of hydrochloric acid = 3.3 grams

    Mass of sodium hydroxide = 6.6 grams

    Molar mass hydrochloric acid (HCl) = 36.46 g/mol

    Molar mass sodium hydroxide (NaOH) = 40.0 g/mol

    Step 2: The balanced equation

    HCl + NaOH → NaCl + H2O

    Step 3: Calculate moles

    Moles = mass / molar mass

    Moles HCl = 3.3 grams / 36.46 g/mol

    Moles HCl = 0.0905 moles

    Moles NaOH = 6.6 grams / 40.0 g/mol

    Moles NaOH = 0.165 moles

    Step 4: Calculate the limiting reactant

    HCl is the limiting reactant. There will react 0.0905 moles. NaOH is in excess. There will react 0.0905 moles moles. There will remain 0.165 - 0.0905 = 0.0745 moles

    Step 5: Calculate moles H2O

    For 1 mol HCl we need 1 mol NaOH to produce 1 mol NaCl and 1 mol H2O

    For 0.0905 moles HCl we'll have 0.0905 moles H2O

    Step 6: Calculate mass H2O

    Mass H2O = moles * molar mass

    Mass H2O = 0.0905 * 18.02 g/mol

    Mass H2O = 1.63 grams

    The theoretical yield of H2O is 1.63 grams

    1.63 g of H₂O is the theoretical yield

    Explanation:

    We determine the reactants for the reaction:

    HCl, NaOH

    We determine the products for the reaction:

    H₂O, NaCl

    The equation for this neutralization reaction is:

    HCl (aq) + NaOH (aq) → NaCl (aq) + H₂O (l)

    We use both masses, from both reactants to determine the limiting.

    First, we convert the mass to moles.

    3.3 g. 1mol / 36.45 g = 0.090 moles of HCl

    6.6 g. 1mol / 40 g = 0.165 moles of NaOH

    Ratio is 1:1, so for 0.165 moles of hydroxide I need the same amount of acid. I have 0.090 HCl so the acid is the limiting reagent.

    Let's work with stoichiometry. Ratio is 1:1, again.

    1 mol of acid can produce 1 mol of water

    Therefore, 0.090 moles of acid must produce 0.090 moles of H₂O

    We convert the moles to mass, to define the theoretical yield

    0.090 mol. 18g / 1 mol = 1.63 g
