Explanation:
Molarity = number of moles / volume
If 550 mL of a 3.50 M KCl solution are set aside and allowed to evaporate until the volume of the solution is 275 mL, which is half of 550 mL, the molarity of the solution with the same number of moles of KCl is 3.5 * 2 = 7.00 M
The molarity of the solution will be 7 M.
What is molarity ?
The total count of moles of solute per liter of a particular solution is known as a solution's molarity.
What is solution?
The volume of just an object is a measurement of how much space it takes up.
Molarity of the solution can be determined by the formula:
[tex]M_{1} V_{1} = M_{2} V_{2}[/tex]
where, M = molarity of solution. V = volume.
Given data:
[tex]M_{1}[/tex] = 3.50 M
[tex]M_{2}[/tex] = ?
[tex]V_{1}[/tex] = 550 mL
[tex]V_{2}[/tex] = 275 mL
Now, put the value of given data in molarity equation.
[tex]V_{2} = M_{1} V_{1} /M_{2}\\V_{2} = (3.50 M) (550 mL) / (275 mL)\\V_{2} = 7 M[/tex]
Therefore, the molarity of the solution will be 7 M.
