A 1.200 liter solution contains 35.0 grams of potassium iodide (KI). What is the molarity of this

enot [183]

Answer:

M = 0.177

Explanation:

First, we have to find the molar mass of potassium iodine (KI).

K = 39.098

I = 126.904

Now, add these values together to get the molar mass of KI

39.098 + 126.904 = 166.0028

Now, it's time to do a grams to moles conversion.

35.0 g KI * $\frac{1 mol KI}{166.0028 g KI}$ = $\frac{35.0}{166.0028}$ = 0.212 mol KI

Now, we can find the molarity of this solution.

Molarity (M) = $\frac{mol}{L}$

M = $\frac{0.212 mol KI}{1.200 L}$ = 0.177 M

The molarity (M) of this solution is 0.177.
