Question

wine is produced by the fermentation of grapes. in fermentation, the carbohydrate glucose is converted to ethanol and carbon dioxide , according to the given balanced equation. how many grams of carbon dioxide are formed from of glucose ? round your answer to significant figures.

Answer 1

To determine the grams of CO2 produced from fermentation of glucose, use the balanced equation for fermentation and stoichiometry to convert the given mass of glucose to the corresponding mass of CO2, ensuring the result is in significant figures.

Step-by-step explanation:

The question revolves around the fermentation process where glucose is converted into ethanol and carbon dioxide (CO2) as a byproduct. This biochemical process, known as anaerobic cellular respiration, is critical in winemaking. To calculate the amount of CO2 produced from glucose, one would use the balanced chemical equation for fermentation:

C6H12O6 → 2 C2H5OH + 2 CO2

This indicates that one mole of glucose produces two moles of carbon dioxide. Given the molecular weights (glucose: 180.16 g/mol, CO2: 44.01 g/mol), you can convert the mass of glucose into moles and then use stoichiometry to find the mass of CO2 produced. This process involves using conversion factors and accounting for significant figures in your calculations.
