a. molecular mass of NO2 = 14 + 2(16) = 46.0 grams / mole Number of moles of NO2 = 60.0 grams X 1 mole / 46.0 grams = 1.30 moles Number of molecules = 1.30 moles X 6.02 Exp 23 molecules / mole = 7.83 Exp 23 molecules b. Number of moles Cl2 = 3.24 Exp 22 molecules / 6.02 Exp 23 molecules / mole = 0.0538 moles Volume of Cl2 = 0.0538 moles X 22.4 liters / mole = 1.21 liter c.
