The molarity (M) of a solution is 11.5 M that contains 0.75 moles of lithium fluoride, LiF in a 65 ml of solution.
What is Molarity ?
Molarity (M) is defined as the number of moles of solute dissolved in 1L of solution. Molarity is also known as Molar concentration. The S.I Unit of Molarity is molar (M) or mol/L.
How to find molarity of a solution ?
Molarity (M) = [tex]\frac{\text{Number of moles of solute}}{\text{Volume of solution (in liters)}}[/tex]
From the above definition it is clear that the volume of solution is in liter. In question the volume of solution is given in ml.
So, convert 65 ml into l.
65 ml = [tex]\frac{65}{1000}[/tex] = 0.065 l
Now, put the values in above formula, we get that
(M) = [tex]\frac{0.75}{0.065}[/tex] = 11.5 M
Thus, the molarity of a solution is 11.5 M that contains 0.75 moles of lithium fluoride, LiF in a 65 ml of solution.
