Question 10
H

In an ammonia plant, 15% of the nitrogen entering the reactor is converted into ammonia each time the gases pass through. N2(g)+3H2(g)⇌2NH3(g)\mathrm{N_{2}(g) + 3H_{2}(g) \rightleftharpoons 2NH_{3}(g)}N2​(g)+3H2​(g)⇌2NH3​(g) Relative atomic masses: H = 1, N = 14

What mass of ammonia is formed when 280 kg of nitrogen passes through the reactor once?
