Answer:

[tex]M=0.0513M[/tex]

Explanation:

Hello!

In this case, since the molarity of a solution is computed by dividing the moles of solute by the volume of solution, we notice we first need the moles of KHP as shown below:

[tex]n=0.5237g*\frac{1mol}{204.22 g} =0.00256mol[/tex]

Next, the volume in liters:

[tex]V=50.0mL*\frac{1L}{1000mL}\\\\V=0.0500L[/tex]

Thus, the molarity turns out to be:

[tex]M=\frac{n}{V}\\\\M=\frac{0.00256mol}{0.05000L} \\\\M=0.0513M[/tex]

Best regards!
