Problem- Calculate mass (g) of HNO3 in a 431.2 g mixture that produced 27.8 L of NO with a total pressure of 0.972 atm at 20 oC. Use the balanced equation. The only source of NO in the mixture is HNO3.
4HNO3(aq) + Al(s) ----> NO(g) + Al(NO3)3(aq) + 2H2O(l)
I want you to elucidate the chemistry in this above problem.
