Question

Calculate the molarity of a solution of monoprotic KHP prepared by mixing a 0.5237 g KHP in 50.0 mL of water .

Answer 1

Answer:

$M=0.0513M$

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:

$n=0.5237g*\frac{1mol}{204.22 g} =0.00256mol$

Next, the volume in liters:

$V=50.0mL*\frac{1L}{1000mL}\\\\V=0.0500L$

Thus, the molarity turns out to be:

$M=\frac{n}{V}\\\\M=\frac{0.00256mol}{0.05000L} \\\\M=0.0513M$

Best regards!
