Calculate the volume of hydrogen generated by the interaction with sodium 101.2 g of technical ethyl alcohol containing 10% of examples.

2C2H5OH + 2Na = 2C2H5ONa + H2
Pure alcohol weight:
m (in-va) * w (pure substance) / 100%
m (C2H5OH) = 101.2 * 0.9 = 91.08 g
n (alcohol) = 91.08 / 46 = 1.98 mol
n (H2) = 0.5n (C2H5OH) = 0.99 mol
V (H2) = 22.4 * 0.99 = 22.176 L
Answer: 22.176 L
