If 3.2 moles of NaCl are dissolved in enough water to make a 0.98-liter solution, what is the molarity of the solution?
M = mols/L solution
I knew that -_-
To find the molarity of a solution, you need two pieces of information: the number of moles of solute and the volume of the solution in liters.
In this case, you are given that 3.2 moles of NaCl are dissolved in enough water to make a 0.98-liter solution. So you have the volume of the solution, which is 0.98 liters.
To find the molarity, you divide the number of moles of solute by the volume of the solution in liters.
So, the molarity (M) of the solution is:
M = moles of solute / volume of solution in liters
M = 3.2 moles / 0.98 liters
M ≈ 3.27 M
Therefore, the molarity of the solution is approximately 3.27 M.
