calculate the molar concentration of 0.1 " AgNO3
0.1 what?
I want to prepare 100 ml of 1nM solution AgNo3. How can get it. pl guide
To calculate the molar concentration of a solution, we need to know the number of moles of the solute (in this case, AgNO3) and the volume of the solution.
Given that the volume of the solution is not provided in your question, I will assume that we need to find the molar concentration of a 0.1 M AgNO3 solution.
The term "0.1 M" refers to the molarity, which represents the number of moles of solute present in one liter (L) of solution. In this case, it means that for every liter of the solution, there are 0.1 moles of AgNO3.
If we know the molar mass of AgNO3, we can calculate the number of moles in 1 L and find the molar concentration.
The molar mass of AgNO3 can be calculated by summing the individual atomic masses of silver (Ag), nitrogen (N), and oxygen (O).
AgNO3 = Ag (1 atom) + N (1 atom) + O (3 atoms)
= (107.87 g/mol) + (14.01 g/mol) + (3 × 16.00 g/mol)
= 107.87 g/mol + 14.01 g/mol + 48.00 g/mol
≈ 169.88 g/mol
Now, to find the molar concentration (C), we divide the number of moles by the volume of the solution in liters (V):
C = moles of solute (n) / volume of solution in liters (V)
In this case, since the given solution has a molarity of 0.1 M, we already know that there are 0.1 moles of AgNO3 in 1 L of the solution.
Therefore, the molar concentration of a 0.1 M AgNO3 solution is 0.1 M.
