A chemist prepares a solution of potassium iodide (KI) by measuring out 67.7. mu mol of potassium iodide into a 400. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mmo1L of the chemist's potassium iodide solution. Round your answer to 3 significant digits.

The concentration of potassium iodide in the solution is

Explanation:

To calculate the molarity of solution, we use the equation:

We are given:

Micro moles of potassium iodide =

Volume of solution = 400 m

Putting values in above equation, we get:

Hence, the concentration of potassium iodide in the solution is
