<u>Answer:</u> The final concentration of potassium nitrate is
<u>Explanation:</u>
To calculate the molecular mass of solute, we use the equation used to calculate the molarity of solution:
We are given:
Mass of potassium nitrate (solute) = 0.360 g
Molar mass of potassium nitrate = 101.1 g/mol
Volume of solution = 500.0 mL
Putting values in above equation, we get:
To calculate the molarity of the diluted solution, we use the equation:
.......(1)
- <u>Calculating for first dilution:</u>
are the molarity and volume of the concentrated
solution
are the molarity and volume of diluted
solution
We are given:
Putting values in equation 1, we get:
- <u>Calculating for second dilution:</u>
are the molarity and volume of the concentrated
solution
are the molarity and volume of diluted
solution
We are given:
Putting values in equation 1, we get:
Hence, the final concentration of potassium nitrate is
