how many moles of NO are formed from 5 moles of NO2 if there is plenty of water present? 3NO2 (g) + H2O (l) = 2HNO3 (aq) + NO (g)

1.67 mole of NO.

Explanation:

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

From the equation above,

3 moles of NO2 produced 1 mole of NO.

Therefore, 5 moles of NO2 will produce = 5/3 = 1.67 mole of NO.

From the calculations made above, 1.67 mole of NO will be produced from 5 moles of NO2
