Hello Ronit,

Sorry, the internet connection is quite erratic while traveling...

Going by the question, it says that each mole of carbon in glucose gets converted into 0.25 moles of carbon in Ethanol

So in my view, one should simply look for how many carbons per mole of glucose get converted into ethanol:

So, for 1 mole of glucose having 6 carbon moles, ethanol shall be able to get 6/4 moles of carbon.

Given this fact, in 1800 gram of glucose (equivalent to 10 moles of glucose), there are 60 moles of carbon (C6H12O6). So, ideally, ethanol should get 60/4 = 15 moles of carbon.

Now, Ethanol is C2H5OH, so it's expected that one should get 7.5 moles of ethanol to satisfy the carbon balance.

So, total ethanol produced should be 7.5 X mol. Wt of ethanol
