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!

  • Chemistry -

    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.
