Find the mass of nitric oxide (V), which is required to obtain 150 g of a nitric acid solution with a mass fraction of HNO3 equal to 10%.
| November 19, 2020 | education
N2O5 + H20 = 2HNO3
1) n (HNO3) = 150 * 0.1 = 15 g.
2) n = 15 \ 63 = 0.24 g / mol
3) n (N205) = 1/2 n (HNO3)
3) m (N205) = 0.12 * 108 = 12.96 g
Answer: 12.96 g
