Calculate the volume, amount of substance and mass of hydrogen, which is formed as a result of the interaction of potassium with water, mass of potassium = 3.9g

2K + 2H2O = 2KOH + H2
the amount of potassium substance is 3.9 / 39 = 0.1 mol
amount of hydrogen substance 0.05 mol
mass of hydrogen 0.05 * 2 = 0.1g
volume 0.05 * 22.4 = 1.12
