How much acetylene will take to obtain 234 kg of benzene?

For this synthesis, the trimerization of acetylene to benzene is used. 3C2H2 = C6H6;

All acetylene is converted to acetylene. Therefore, to obtain 234,000 grams of benzene, it is necessary to use 234,000 grams of acetylene.

Let’s calculate the available chemical amount of acetylene.

To do this, we divide the mass of acetylene by its molar mass.

M C2H2 = 12 x 2 + 1 x 2 = 26 grams / mol;

N C2H2 = 234,000/26 = 9000 mol;

Let’s calculate its volume by multiplying the amount of the substance by the volume of 1 mol of the gaseous substance.

V C2H2 = 9000 x 22.4 = 201 600 liters;
