Answer to Question #318170 in Inorganic Chemistry for Nolley

Question

Ammonium nitrate is produced when ammonia is combined with concentrated nitric acid as shown in the following balanced equation: NH,(aq) + HNO,(aq) — NH,NO)(aq) In an experiment, 404.2 g of ammonium nitrate is produced when 112.5 g of ammonia and excess nitric acid are combined. Determine the percentage yield of the product.

Answer 1

NH₃(aq) + HNO₃(aq) — NH₄NO₃(aq)

n_t (NH₄NO₃) = n_t (NH₃) = 112.5 g/ 17 g/mol = 6.62 mol

m_t (NH₄NO₃) = n_t (NH₄NO₃)* M(NH₄NO₃) = 6.62 mol* 80 g/mol = 529.6 g

m_pr (NH₄NO₃) = 404.2 g

w(NH₄NO₃) = m_pr (NH₄NO₃)/ m_t (NH₄NO₃) = 404.2 g/ 529.6 g = 0.76 (76%)

Answer: 0.76 (76%)
