When the glucose became sour, 115 g of alcohol were taken. Read off the volume of carbon dioxide gas that has formed as a result of the reaction.

The glucose fermentation reaction is recorded:

C6H12O6 = 2C2H5OH + 2CO2.

The mass of one mole of alcohol: 12 * 2 + 1 * 5 + 16 + 1 = 46 g.

The mass of one mole of carbon dioxide is 12 + 16 * 2 = 12 + 32 = 44 g.

Let’s calculate how many grams of carbon dioxide will be obtained as a result of the reaction:

92 g of alcohol – 88 g of carbon dioxide;

115 g of alcohol – x g of carbon dioxide.

x = 115 * 88/92 = 110 g.

Let’s find the volume.

44 g of gas – 22.4 liters;

110 g of gas – x l.

x = 110 * 22.4 / 44 = 56 liters.
