Answer to Question #87612 in General Chemistry for Hayleigh

Question

Aqueous hydrochloric acid reacts with solid sodium hydroxide to produce aqueous sodium chloride and liquid water . What is the theoretical yield of water formed from the reaction of 33.2 g of hydrochloric acid and 13.1 g of sodium hydroxide? Round your answer to 3 significant figures.

Answer 1

$NaOH+HCl \to NaCl+H2O$

$n(NaOH)=\dfrac{13.1g}{40g/mol}=0.3275mol$

$n(HCl)=\dfrac{33.2g}{36.46g/mol}=0.9106mol$

NaOH is then the limiting reagent.

Theoretical yield$(H2O)=\dfrac{13.1g*18g/mol}{40g/mol}=5.90g$

Answer: theoretical yield(H₂O) = 5.90g
