Calculate the volume of gas and the mass of salt, which are formed by dissolving 180 g of cupronickel alloy containing 25% nickel in sulfuric acid.
Ni + 2H2SO4 = NiSO4 + SO2 + 2H2O
1) 180 * 0.25 = 45 (g)
2) 45/59 = 0.7627 (mol)
3) 0.7627 * 155 = 118.22 (g)
4) 0.7627 * 22.4 = 17 (l)
Answer: 17 liters
