Determine the amount of carbon dioxide that is produced when 28 g of carbon is burned. the product yield is 75%.

Equation of obtaining carbon dioxide:

C + O2 = CO2.

Determine the amount of moles of carbon that reacts:

n (C) = m / M = 28/12 = 2.3 mol.

It can be seen from the reaction equation that the amount of moles of the starting materials and the reaction product are equal, which means:

n (C) = n (CO2).

If at 100% product yield the number of moles is 2.3,

then at 75% yield – x mol.

x = 75 * 2.3 / 100 = 1.75 mol.

The volume of the generated carbon dioxide under normal conditions will be:

V = n • Vm = 1.75 • 22.4 = 39.2 liters.
