Hey could anyone please help me with this question from the 2010 Chemistry HSC paper.

What mass of ethanol is obtained when 5.68 g of carbon dioxide is produced during
fermentation, at 25°C and 100 kPa?
(A) 2.95 g
(B) 5.95 g
(C) 33.6 g
(D) 147.2 g

The Answers B thanks.

What i tried to do was 5.68/44.06 = 0.128... moles CO2
moles ratio 2:2 so 0.128.. moles of ethanol x 24.79 = 3.1958... L
I know it's way too big and just wondering what I'm forgetting to do/doing wrong

C₆H₁₂O₆ 2C₂H₅OH+2CO₂
n=m/M
n=5.68/44 = 71/550
Ethanol molar mass = 46
m= n*M
m= 71/550 * 46
m= 5.94g
