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

Dec 5, 2016

50.3% yield

#### Explanation:

Let's start by finding the balanced chemical reaction:

C_6H_12O_6 → 2 C_2H_5OH + 2 CO_2

Remember that the percent yield is the actual yield divided by the theoretical yield multiplied by 100.
