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.

Aphelion in miles =94290301

Perihelion in miles = 91200281

Explanation:

To convert km in mile we use the multiply the distance in km with 0.62, because there are 0.62 miles in 1 km.

Aphelion in miles = aphelion in km × 0.62

Aphelion in miles = 152081132 × 0.62

Aphelion in miles =94290301

Perihelion in miles = perihelion in km × 0.62

Perihelion in miles = 147097229 × 0.62

Perihelion in miles = 91200281
