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

dynamic equilibrium is the answer.
