It is necessary to obtain 4.4 g of acetaldehyde using the reaction of interaction of acetylene with water. How much acetylene will react?

The reaction of obtaining acetaldehyde (CH3-COH) from acetylene (C2H2) is Kucherov’s reaction.
Given:
m (CH3-COH) = 4.4 g
V (C2H2) = x l
Decision.
The molar volume of any gas is 22.4 l / mol.
Molar mass of СН3-СОН = 12 * 2 + 1 * 4 + 16 = 44 g / mol
Let’s write the reaction equation:
C2H2 + H2O = CH3-COH.
According to the reaction equation, 44 g of CH3-COH are obtained from 22.4 liters of C2H2, and 4.4 g of CH3-COH are obtained from chl C2H2 according to the reaction condition. We make the proportion and find x.
x = 22.4 * 4.4 / 44 = 2.24 liters.
Answer: the volume of acetylene is 2.24 l
