Find the volume of hydrogen that is obtained by decomposing 2 mol of water.

univerkov | December 8, 2020 | education

2H2O = 2H2 + O2
To get two moles of water, we need 2 moles of hydrogen and 1 mole of oxygen. Therefore, (let nude be α)
α = m / Mr
m = Mr * α = 2 * 2 = 4 (g) = 0.004 (kg)
Then the volume:
V = m / p = 0.004 / 0.090 = 0.04
Answer: V = 0.04
