Determine the amount of carbon dioxide that will result from the combustion of 184 g of ethanol?

1. Combustion of ethanol is described by the reaction equation:

C2H5OH + 2O2 → CO2 + 3H2O;

2.Calculate the chemical amount of ethanol:

n (C2H5OH) = m (C2H5OH): M (C2H5OH);

M (C2H5OH) = 2 * 12 + 5 + 16 + 1 = 46 g / mol;

n (C2H5OH) = 184: 46 = 4 mol;

3.The amounts of released carbon dioxide and combustible ethanol by the reaction coincide:

n (CO2) = n (C2H5OH) = 4 mol;

4. find the volume of carbon dioxide:

V (CO2) = n (CO2) * Vm = 4 * 22.4 = 89.6 liters.

Answer: 89.6 liters.
