What is the mass of acetylene obtained when interacting with water 100 g of technical calcium

What is the mass of acetylene obtained when interacting with water 100 g of technical calcium carbide CaC2, containing 4% of impurities.

The reaction for the synthesis of acetylene from calcium carbide is described by the following chemical reaction equation:

CaC2 + 2H2O = C2H2 + Ca (OH) 2;

From 1 mole of calcium carbide, 1 mole of acetylene is synthesized.

Let’s calculate the available chemical amount of silicon carbide substance.

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

N CaC2 = 100 x 0.96 / 64 = 1.5 mol;

The same amount of acetylene will be synthesized.

Let’s define its volume. To do this, multiply the amount of substance by the standard volume of 1 mole of gaseous substance, which is 22.4 liters.

V C2H2 = 1.5 x 22.4 = 33.6 liters;
