Sally has constructed a concentration cell to measure Ksp for MCln. She constructs the cell by adding 2 mL of 0.05 M M(NO3)n to one compartment of the microwell plate. She then makes a solution of MCln by adding KCl to M(NO3)n. She adds 6.380 mL of the resulting mixture to a second compartment of the microwell plate. Sally knows n (the charge on the metal ion) = +2
She has already calculated [Mn+] in the prepared MCln solution using the Nernst equation. [Mn+] = 8.279 M

Required:
How many moles of [Cl-] must be dissolved in that compartment?

0.1056 mole

Explanation:

As Sally knows that the charge on the metal ion is n = +2

In that compartment

The volume of the taken in that compartment = 6.380 mL

So, the number of moles of

                                                      = 52.82 m mol

                                                      = 0.05280 mol

But n = 2

Therefore, moles of = 2 x moles of

                                       = 2 x 0.05282

                                       = 0.1056 mole

(b) which contains higher levels of vitamin b, oranges or spinach?

you can eliminate a, c, and d because they are questions based on opinions.
