How many kilograms of ethanol is produced from 1 kilogram of glucose in ethanol fermentation?

1. 2.00
2. 0.20
3. 0.51
4. 0.05

Correct Option: C

C₆H₁₂O₆ + Zymase → 2 C₂H₅OH + 2 CO₂ use mass balance process to calculate the ethanol production.
180g of Glucose yields = 92 g of ethanol
Therefore, 1000g of glucose yields = 92 / 180 * 1000 = 0.51 kg
