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%
