Determine the mass of carbon monoxide that is formed during the combustion of C2H2 with a mass of 260 g

To solve, we write down the equation of the process:

2С2Н2 + 5О2 = 4СО2 + 2Н2О + Q – combustion, carbon monoxide is released (4);
We make calculations:
M (C2H2) = 26 g / mol;

M (CO2) = 44 g / mol.

Determine the amount of the original substance:
Y (C2H2) = m / M = 260/26 = 10 mol.

4. Proportion:

10 mol (C2H2) – X mol (CO2);

-2 mol 4 mol from here, X mol (CO2) = 10 * 4/2 = 20 mol.

Find the mass of the product:
m (CO2) = Y * M = 20 * 44 = 880 g

Answer: received carbon dioxide weighing 880 g
