Chapter 14, Problem 24CI

In wine-making, glucose $\left(C_6{H}_{12}{O}_6\right)$ from grapes undergoes fermentation in the absence of oxygen to produce ethanol and carbon dioxide. A bottle of vintage port wine has a volume of 750 mL and contains 135 mL of ethanol $\left({\text{C}}_{\text{2}}{\text{H}}_{\text{6}}\text{O}\right)$ . Ethanol has a density of 0.789 g/mL. In 1.5 lb of grapes, there are 26 g of glucose. (2.7, 7.2, 7.3, 8.2, 9.2, 12.4)

1. Calculate the volume percent (v/v) of ethanol in the port wine.
2. What is the molarity (M) of ethanol in the port wine?
3. Write the balanced chemical equation for the fermentation reaction of sugar in grapes.
4. How many grams of sugar from grapes are required to produce one bottle of port wine?
5. How many bottles of port wine can be produced from
1.0 ton of grapes (1 ton = 2000 lb) ?
