Find the volume of hydrogen that fully reacts with 0.6 mol oxygen.

1. We draw up a chemical equation according to the condition, not forgetting to put down the coefficients:
2H2 + O2 = 2H2O.
2. The equation goes:
n (H2) = n (O2) * 2 = 0.6 * 2 = 1.2 mol, where n is the amount of substance.
3. The volume is found by the formula:
V (H2) = n (H2) * Vm, where V is the volume, n is the amount of substance, Vm is the molar volume.
4. Substitute the values into the formula:
V (H2) = 1.2 * 22.4 = 26.88 liters.
Answer: Volume = 26.88 liters.
