HCl + NaOH → NaCl + H2O

1. If 30g of HCl is reacted with excess NaOH, and 10g of NaCl is produced, what is the theoretical yield of the experiment?

2. If 30 g of HCl is reacted with excess NaOH, and 10 g of NaCl is produced, what is the percent yield of the experiment?

    Answer and Explanation:

    Equation: HCl + NaOH → NaCl + H2O

    Calculation of Part 1.

    Number of moles of HCl = 30 divided by 36.46 = 0.823 moles.

    Number of moles of NaCI that are produced = 0.823 moles

    Theoretical weight of product formed = 0.823 multiply 58.44 = 48.08 gms.

    Thus, theoretical yield = 48.08 gms.

    Calculation of Part 2.

    Yield of NaCI = 10 grams.

    Percent yield is equal to 10 divided by 48.08 multiply with 100

    = 20.8%
