Answer:

4.7 Liters of NO2

Explanation:

mole weight of HNO3  (from periodic table) = ~~ 63 gm/mole

  12 grams of this is   12/63 = .19047 mole

From the equation, you should be able to see that 3 moles of NO2 produces 2 moles of HNO3

  so you need  3/2 * moles HNO3 = .2857 moles of NO2 needed

PV = nR T     n = moles   R = .082057 L-atm/(k-mole)    25 C = 298.15 K

1.6 (V) = .2857 (.082057)(298.15)

  solve for V = 4.37 liters of NO2
