| The reaction equation for alcoholic fermentation can be written as follows:
С6Н12О6 = 2 С2Н5ОН + 2 СО2
The molar mass of ethanol is 46 g / mol; the molar volume of carbon dioxide is 22.4 l / mol (according to Avogadro’s law).
For a competent decision, we translate the units of mass: 0.23 kg. = 230 g.
Based on the equation, we will compose the proportion:
230 g of ethanol corresponds to X l. carbon dioxide as
2 * 46 g / mol of ethanol correspond to 2 * 22.4 l / mol of carbon dioxide.
X = (230 * 2 * 22.4) / (2 * 46) = 112 liters.
Answer: the volume of carbon dioxide is 112 liters.
