Question

(a) if 200.0 g of glucose is fully converted, what will be the total mass of ethanol and carbon dioxide produced?

Answer 1

Answer:

             Ethanol =  102.29 g

             Carbon Dioxide =  97.71 g

Solution:

The Balance Chemical Equation for the fermentation of Glucose is as follow,

                                  C₆H₁₂O₆    →    2 C₂H₅OH  +  2 CO₂

Mass of Ethanol produced:

According to equation;

       180.156 g (1 mole) C₆H₁₂O₆ produces  =  92.14 g (2 moles) of C₂H₅OH

So,

                  200 g of C₆H₁₂O₆ will produces  =  X g of C₂H₅OH

Solving for X,

                      X  =  (200 g × 92.14 g) ÷ 180.156 g

                      X  =  102.29 g of C₂H₅OH

Mass of Carbon Dioxide produced:

According to equation;

       180.156 g (1 mole) C₆H₁₂O₆ produces  =  88.02 g (2 moles) of CO₂

So,

                  200 g of C₆H₁₂O₆ will produces  =  X g of CO₂

Solving for X,

                      X  =  (200 g × 88.02 g) ÷ 180.156 g

                      X  =  97.71 g of CO₂
