A 1.00-mole sample of C6H12O6 was placed in a vat with 100 g of yeast. If 32.3 grams of C2H5OH was obtained, what was the percent yield of C2H5OH?

Respuesta :

Answer:

y = 35.06 %.

Explanation:

The reaction of fermentation is:

C₆H₁₂O₆  →  2C₂H₅OH + 2CO₂      (1)        

From the reaction (1) we have that 1 mol of C₆H₁₂O₆ produces 2 moles of C₂H₅OH, then the number of moles of C₂H₅OH is:

[tex]n = \frac{2 moles C_{2}H_{5}OH}{1 mol C_{6}H_{12}O_{6}}*1 mol C_{6}H_{12}O_{6} = 2 moles C_{2}H_{5}OH[/tex]

Now, we need to find the mass of C₂H₅OH:

[tex]m = n*M = 2 moles*46.07 g/mol = 92.14 g[/tex]  

Finally, the percent yield of C₂H₅OH is:

[tex] \% = \frac{32.3 g}{92.14 g}*100 = 35.06 \% [/tex]

Therefore, the percent yield of C₂H₅OH is 35.06 %.

I hope it helps you!

The percent yield of C2H5OH should be 35.06% also it have the 1.00 moles.

Calculation of the percent yield:

Since

The reaction of fermentation should be

C₆H₁₂O₆  →  2C₂H₅OH + 2CO₂      (1)        

Here  1 mol of C₆H₁₂O₆ generated 2 moles of C₂H₅OH, so the number of moles of C₂H₅OH should be

= 2 moles / 1mole * 1 mole

= 2 moles C₂H₅OH

So here the percent yield should be

= 32.3 / (2 * 4607)

= 32.3 / 92.14

= 35.06%

Hence, The percent yield of C2H5OH should be 35.06% also it have the 1.00 moles.
