Prin fermentatia a 10 moli de glucoza cu un randament de 50% rezulta un nr de moli de etanol egal cu?

Răspuns :

C₆H₁₂O₆ = 2CH₃-CH₂-OH + 2CO₂

m glucoza = 10*180=1800g 

180g C₆H₁₂O₆..............2*46g C₂H₅-OH
1800g.............................x=920g (mt)

η = mp/mt*100=>mp=η*mt/100 =  50*920/100=460g C₂H₅-OH

n=m/M=460/46 = 10 moli C₂H₅-OH
