An alcoholic fermentation was conducted in the laboratory using glucose as substrate with a working volume of 1,500 mL. After 5 days of fermentation, 11% by volume C2H5O was produced. Assuming that the sugar is completely fermented to ethanol and no volume changed during fermentation. Calculate the following: a. Volume of ethyl alcohol in liters produced. b. Mass (g) of C2H5OH. The density of ethyl alcohol is 0.79 g/mL. c. Moles of i) C6H12O6, ii) C2H5OH, and iii) CO2. d. Mass of C6H12O6 used as substrate. e. Volume of carbon dioxide in liters produced. 1 mole of an ideal gas is equal to 22.4 L at standard temperature and pressure (STP). Molar mass: C6H12O6 – 180.156 g/ml; C2H5OH = 46.07 g/ml; CO2 = 44.01 g/ml Chemical reaction of ethyl alcohol fermentation: C6H12O6(aq) ----> 2 C2H5OH(aq) + 2 CO2(g)

Question
. An alcoholic fermentation was conducted in the laboratory using glucose as substrate with a working volume of 1,500 mL. After 5 days of fermentation, 11% by volume C2H5O was produced. Assuming that the sugar is completely fermented to ethanol and no volume changed during fermentation. Calculate the following:
a. Volume of ethyl alcohol in liters produced.
b. Mass (g) of C2H5OH. The density of ethyl alcohol is 0.79 g/mL.
c. Moles of i) C6H12O6, ii) C2H5OH, and iii) CO2.
d. Mass of C6H12O6 used as substrate.
e. Volume of carbon dioxide in liters produced. 1 mole of an ideal gas is equal to 22.4 L at
standard temperature and pressure (STP).
Molar mass: C6H12O6 – 180.156 g/ml; C2H5OH = 46.07 g/ml; CO2 = 44.01 g/ml
Chemical reaction of ethyl alcohol fermentation:
C6H12O6(aq) ----> 2 C2H5OH(aq) + 2 CO2(g)
