Fermentation of glucose question help. (1 Viewer)

I need help on how to work out this question, I thought it was as simple as converting mass of CO2 to moles and using ratios but the answer I got wasn't the correct answer.

C6H12O6 -> 2co2 + 2c2h5oh
molar ratio b/w co2 and ethanol is 1:1
n (co2)= 5.68/44 = 0.129... moles = n (ethanol)
m (ethanol) = 0.129 x MM (Ethanol) = 0.129 x 46 = 5.938..g

Should be correct, I also got B

Ah that's what I forgot to do, I forgot to multiply the molecular weight of ethanol after finding the moles, lol, my bad.
