What mass of acetic acid can be obtained from 112 liters of acetylene?

To solve, we write down the equations of the processes:

С2Н2 + Н2О = Н2С = СНОН (vinyl alcohol) = Н3С – СОН – hydration, ethanal was formed;
СН3 – СОН + Ag2O = CH3COOH + 2Ag – qualitative reaction to aldehyde, acetic acid is released.
Calculations:
M (C2H2) = 26 g / mol;

M (CH3COOH) = 60 g / mol.

4. Proportion:

1 mol of gas at normal level – 22.4 liters;

X mol (C2H2) – 112 liters from here, X mol (C2H2) = 1 * 112 / 22.4 = 5 mol;

Y (CH3COOH) = 5 mol since the amount of substances is 1 mol.

Find the mass of acid:
m (CH3COOH) = Y * M = 5 * 60 = 300 g

Answer: the mass of acetic acid is 300 g
