Question

A.   Determine how much vinegar in gal. is required to react with an iron nail to produce 32.5 g of hydrogen. The density of HC₂H₃O₂ is 1.053 g/ml.

Answer 1

2Fe + 6HC₂H₃O₂ → 2Fe(C₂H₃O₂)₃ + 3H₂

Moles of hydrogen = $\frac{32.5}{2}=16.25moles$

Moles of HC₂H₃O₂ $=\frac{6}{3}×16.25=32.5moles$

Mass $=60×32.5=1950grams$

Volume $=\frac{1950}{1.053}=1851.9ml$
