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

`M=0.0513M`

Step-by-step 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*(1mol)/(204.22 g) =0.00256mol`

Next, the volume in liters:

`V=50.0mL*(1L)/(1000mL)\\\\V=0.0500L`

Thus, the molarity turns out to be:

`M=(n)/(V)\\\\M=(0.00256mol)/(0.05000L) \\\\M=0.0513M`

Best regards!
