Answer: The concentration of solution is 0.35 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]

where,

n = moles of solute

[tex]V_s[/tex] = volume of solution in ml = 200

moles of [tex]KCl[/tex] = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{5.2g}{74.5g/mol}=0.070mol[/tex]

Now put all the given values in the formula of molality, we get

[tex]Molarity=\frac{0.070\times 1000}{200}[/tex]

[tex]Molarity=0.35M[/tex]

Therefore, the concentration of solution is 0.35 M
