Answer 1

In the preparation of HNO₃, we get NO gas by catalytic oxidation of ammonia. The moles of NO produced by the oxidation of two moles of NH₃ will be two.

Explanation:

Two moles of NH₃ will produce 2 moles of NO on catalytic oxidation of ammonia in preparation of nitric acid

\[\ce{4NH3 + 5O2 ->[Δ][Pt(Rh gauge catalyst)] 4NO(g) + 6H2O(l)}\]

Hence, 2 moles of ammonia will produce 2 moles of No.
