FAQ
What is the concentration of the Potassium Permanganate solution that would be prepared with
3.161g of KMnO4 to make a 0.1N solution of 1L?
The concentration of the Potassium Permanganate solution prepared with 3.161g of KMnO4 to make a 0.1N solution of 1L can be calculated as follows:
First, determine the molar mass of KMnO4:
K (Potassium) = 39.1 g/mol
Mn (Manganese) = 54.9 g/mol
O (Oxygen) = 16.0 g/mol
Molar mass of KMnO4 = 39.1 + 54.9 + (4 x 16.0) = 158.0 g/mol
Next, calculate the number of moles of KMnO4 in 3.161g:
Moles = Mass / Molar mass = 3.161g / 158.0 g/mol = 0.02 mol
Finally, calculate the concentration of the solution in terms of Normality (N):
N = Moles / Volume (in L)
N = 0.02 mol / 1 L = 0.02 N
Therefore, the concentration of the Potassium Permanganate solution prepared with 3.161g of KMnO4 to make a 0.1N solution of 1L is 0.02 N.
How can I prepare a 0.1N solution of Potassium Permanganate using 3.161g of KMnO4?
To prepare a 0.1N solution of Potassium Permanganate using 3.161g of KMnO4, follow these steps:
1. Calculate the molar mass of KMnO4 (as done in the previous question).
2. Determine the number of moles of KMnO4 in 3.161g (as done in the previous question).
3. Calculate the volume of the solution needed for a 0.1N concentration:
Volume (in L) = Moles / N = 0.02 mol / 0.1 N = 0.2 L
4. Since you want to prepare 1L of the solution, you will need to dilute the 0.2L solution with distilled water to achieve a total volume of 1L.
5. Mix the 0.2L solution of Potassium Permanganate with 0.8L of distilled water to obtain a 0.1N solution of 1L.
