1. Find the molar mass of NO2 (46.01)
2. Find the number of moles in 25 g of NO2 (by dividing 25 by the molar mass) 25/46.01 = .54
3. For every 3 moles of NO2 there are 2 moles of HNO3. multiply the number of moles of NO2 by 2/3
.54 x 2/3 = .36
4. Finally, multiply this number by the molar mass of HNO3 (63.018)
.36 x 63.018 = 22.68 g HNO3
