Question: In a binary solution of A and B, if the mole fraction of A is 0.6, what is the mole fraction of B?
Options:
0.4
0.6
1.0
0.2
Correct Answer: 0.4
Solution:
The mole fraction of B can be calculated as 1 - mole fraction of A = 1 - 0.6 = 0.4.

Questions & Step-by-Step Solutions
In a binary solution of A and B, if the mole fraction of A is 0.6, what is the mole fraction of B?
Step 1: Understand that the mole fraction of a component in a solution is a way to express how much of that component is present compared to the total amount of all components.
Step 2: Know that in a binary solution (which has only two components, A and B), the sum of the mole fractions of A and B must equal 1.
Step 3: Since the mole fraction of A is given as 0.6, we can use this information to find the mole fraction of B.
Step 4: Use the formula: mole fraction of B = 1 - mole fraction of A.
Step 5: Substitute the value of the mole fraction of A into the formula: mole fraction of B = 1 - 0.6.
Step 6: Calculate the result: mole fraction of B = 0.4.
Mole Fraction – The mole fraction is a way of expressing the concentration of a component in a mixture, calculated as the ratio of the number of moles of that component to the total number of moles of all components.
