The formula for the calculation of moles is shown below:
Thus,
Given, Mass of = 125.5 g
Molar mass of = 46.07 g/mol
The formula for the calculation of moles is shown below:
Thus,
So, according to definition of mole fraction:
<u>Answer:</u> The correct answer is Option 5.
<u>Explanation:</u>
- To calculate the molarity of the solution after mixing 2 solutions, we use the equation:
where,
are the n-factor, molarity and volume of the NaOH.
are the n-factor, molarity and volume of the
We are given:
Putting all the values in above equation, we get:
