Answer :
0.6 molar is the molarity of the solution after dilution
Only the volume in which they are dissolved affects the number of moles of KCl in the solution.
Moles of solute divided by Liters of solution equals molarity, or M.
M1V1 = M2V2
is the formula to calculate the concentration.
where V1 and V2 are the initial and final volumes and M1 and M2 are the initial and final concentrations, respectively.
Given the dilution formula, we can solve for M2 by plugging in our existing data.
Since we will have the same number of moles in a bigger volume of solution, we anticipate a reduction in concentration.
Instead of using volumes in litres, we can utilise mL.
(4.00 M)(75.0 mL) = M2(500 mL)
M2 = 300/500
M2 = 0.6 M
M2 = 0.600 M
