I need help on this stoichiometry problem. I don't know whay my answer is incorrect.
The fermentation of sugar to produce ethyl alcohol occurs by the following reaction:
C6H12O6 -- 2C2H5OH + 2CO2
What mass of ethyl alcohol can be made from 1.00 kg of sugar?
I keep getting 1012.32 g, but the solution says 511g. please help!
And 511 it is.
moles sugar = 1000g/molar mass sugar = ??
moles ethyl alcohol produced = 2 x moles sugar.
mass ethyl alcohol = moles x molar mass.
