Answer:

#C_6H_12O_6(aq) rarr 2C_2H_5OH(aq) + 2CO_2(g)#

Explanation:

Molecular mass of ethanol, #46.07# #g*mol^-1#.

We require, #(122.0*g)/(46.07*g*mol^-1# #=# #2.65# #mol# ethanol.

Given that 1 mol of glucose gives 2 moles of ethyl alcohol upon fermentation, we need to ferment at least #1.33# #mol# of sugar. What is this amount in grams?
