Answer:
PI = 6.04
In the attached figure are the missing hydrogen atoms
Explanation:
Given both pk, the isoelectric point will be equal to:
PI = (1/2)*(pka + pka2), where pka = 2.32 and pka2 = 9.76
PI = (1/2)*(2.32 + 9.76) = 6.04
Considering the definition of mole fraction, the mole fraction of each component in the solution is:
- CH₃OH: 0.54
- CHCl₃: 0.118
- C₃H₇OH: 0.342
The molar fraction is a way of measuring the concentration that expresses the proportion in which a substance is found with respect to the total moles of the solution.
<h3>Mole fraction of each component</h3>
In this case, in first place you should know that the molar mass of each component is:
- CH₃OH: 32
- CHCl₃: 121.35
- C₃H₇OH: 60
Now, the number of moles of each compound can be calculated as:
- CH₃OH:
= 1.3125 moles
- CHCl₃:
= 0.2884 moles
- C₃H₇OH:
= 0.8333 moles
So, the total moles of the solution can be calculated as:
Total moles = 1.3125 moles + 0.2884 moles + 0.8333 moles
<u><em>Total moles = 2.4342 moles</em></u>
Finally, the more fraction of each component can be calculated as follow:
- CH₃OH:
= 0.54
- CHCl₃:
= 0.118
- C₃H₇OH:
= 0.342
In summary, the mole fraction of each component in the solution is:
- CH₃OH: 0.54
- CHCl₃: 0.118
- C₃H₇OH: 0.342
