Nitric acid is not merely a strong acid however also a strong oxidizing agent. In hot concentrated acid solution, the reaction with zinc is
3 Zn(s) + 8 HNO3 3 Zn(NO3)2(aq) + 2 NO(g) + 4 H2O
Compute the mass of Zn(s) necessary to produce 4.4 g of NO(g) when the metal comes into contact with excess nitric acid.
