Answer:
[tex]255.71~g~C_2H_5OH[/tex]
Explanation:
First, we have to check if the reaction is balanced:
[tex]C_6H_1_2O_6_(_s_)~->~2C_2H_5OH_(_l_)~+~2CO_2_(_g_)[/tex]
We have 6 carbon atoms on both sides, 12 hydrogens, and 6 oxygens. So, we can continue with the problem. If we want to calculate the mass of ethanol ([tex]C_2H_5OH[/tex]) we need to know:
1) Molar mass of glucose ([tex]C_6H_12O_6[/tex])
In this case, we have to know the atomic mass of each atom:
-) C 12 g/mol
-) O 16 g/mol
-) H 1 g/mol
With the formula we can calculate the molar mass:
(12*6) + (16*6) + (1*12) = 180 g/mol
2) Molar ratio between glucose and ethanol
In the balanced equation we have 1 mol of [tex]C_6H_12O_6[/tex] and 2 moles of [tex]C_2H_5OH[/tex]. So the molar mass is 1:2
3) Molar mass of ethanol ([tex]C_2H_5OH[/tex])
With the formula, we can calculate the molar mass:
(12*2) + (6*1) + (16*1) = 46 g/mol
Finally, we can to the calculation:
[tex]500.0g~C_6H_12O_6\frac{1mol~C_6H_12O_6}{180g~C_6H_12O_6}\frac{2mol~C_2H_5OH}{1mol~C_6H_12O_6}\frac{46g~C_2H_5OH}{1mol~C_2H_5OH}=255.71g~C_2H_5OH[/tex]
I hope it helps!
The branch of science which deals with chemicals and bonds is called chemistry.
The correct answer for the question is 255g of ethanol.
The process of digesting the glucose in absence of oxygen is called fermentation.
Before solving the question, we must check the atoms of compound and balanced it.
The molar mass of the glucose is as follows:
- [tex]C_6H_12O_6 = (12*6) + (16*6) + (1*12) = 180 g/mol[/tex].
After balancing the equation, the mole ratio of the glucose vs ethanol is 1:2
The molar mass of the ethanol is as follows:-
[tex]C_2H_5OH[/tex] =[tex]12*2) + (6*1) + (16*1) = 46 g/mol[/tex]
After diving each molar mass of each compound with respect to its mole ratio. The mass of the ethanol produced is 255g.
Hence, the correct answer is 255g.
