6.4 calcium carbide was dissolved in water, how much acetylene is released in this case

Acetylene is synthesized by the interaction of calcium carbide with water.

CaC2 + 2H2O = Ca (OH) 2 + C2H2 ↑;

Let’s calculate the molar amount of calcium carbide.

To do this, let’s summarize the molar weights of the elements that make up this molecule.

M CaC2 = 40 + 12 x 2 = 64 grams / mol;

N CaC2 = 6.4 / 64 = 0.1 mol;

Theoretically, the same molar amount of acetylene will be obtained.

Let’s define its volume. For this purpose, we multiply the molar amount of the substance by the volume of 1 mole of the substance (which is 22.4 liters).

V C2H2 = 0.1 x 22.4 = 2.24 liters;
