You have been given a sample of unknown molarity. Calculate the molarity of a solution which has been prepared by dissolving 8.75 moles of sodium chloride in enough water to produce a solution of 6.22l.
M=molessalt/volumesolution
To calculate the molarity of a solution, you need to divide the number of moles of solute by the volume of the solution in liters.
Given:
Number of moles of sodium chloride (NaCl) = 8.75 moles
Volume of the solution = 6.22 L
Molarity (M) = Moles of solute (NaCl) / Volume of solution (L)
Therefore, the molarity of the solution is calculated as follows:
Molarity (M) = 8.75 moles / 6.22 L ≈ 1.407 M
So, the molarity of the solution prepared by dissolving 8.75 moles of sodium chloride in enough water to produce a solution of 6.22 liters is approximately 1.407 M.
