Calculate the volume of gas that will be released if 5 gr. sodium to dissolve in 200 gr. 50% sulfuric acid solution?

2Na + H2SO4 = Na2SO4 + H2.
1) Molar mass of sodium: 23.
2) The amount of sodium substance: 5/23 = 0.22 mol.
3) Mass of sulfuric acid solute: 200 * 50/100 = 100g.
4) Molar mass of sulfuric acid: 2 + 32 + 64 = 98.
5) Amount of sulfuric acid substance: 100/98 = 1.02 mol.
Lack of sodium. The calculation is carried out on it.
6) According to the reaction equation, there is one mole of hydrogen for two moles of sodium. This means that the amount of hydrogen substance is: 0.22 * 2 = 0.44 mol.
7) The volume of hydrogen: 0.44 * 22.4 = 9.856 liters – the answer.
