# Write the balanced chemical equation for the biosynthesis of

Please help with the following problem.

Write the balanced chemical equation for the biosynthesis of ethanol. Label the sucrose and the ethanol in the equation.

If you start with one mol sucrose, how many mol ethanol is produced? (Assume complete conversion of sucrose to ethanol.)

The density of ethanol is 0.80 g/ml. Assume that you obtained 5.0 mL of distilled ethanol. What is the yield in grams? What is the yield in mols? (Show work)

Assuming that you obtained 5.0 mL of ethanol, what is the percent yield? (Show work)

Describe the ignition of your product. What does the term proof mean when referring to alcoholic beverages? What is the relationship between proof and % alcohol? (Show work)

#### Solution Preview

Balanced equation

C12H22O11 + H2O = 4CH3CH2OH + 4CO2

C12H22O11 = sucrose

CH3CH2OH = ethanol

Assuming complete conversion, each mole of sucrose will produce 4 moles of ethanol.

The density of ethanol is 0.80 ...
