Question

How many moles (precise to the nearest 0.01 mol) of nitric acid are produced from 300.00 mol of nitrogen dioxide?

Answer 1

      3 NO2(g) + H2O(l) -> 2 HNO3 (aq) + NO (g)

From 3 moles of nitrogen dioxide you get 2 moles of nitric acid. Therefore,

3:2=300:x
x=200 moles
x- moles of nitric acid

Answer 2

200 mol is the correct answer
