Saccharomyces cerevisiae produces ethanol by fermentation.

Saccharomyces cerevisiae produces ethanol by fermentation. The theoretical yield of ethanol from 2.5 g of glucose is ______ g.

C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂
180 2 × 46 = 92

So, Yield =	92	g ethanol / g glucose
	180

So, for 2.5 gm = 2.5 ×	92	= 1.27 gm
	180
