Acontainer has 800.0 ml of an aqueous solution containing k+ ions. how many grams of k+ ions are in the solution if the molarity is 0.649 m?

There are 20.24 grams of in the solution if the molarity is 0.649 M.

Explanation:

Molarity equals number of moles in a liter of solution as follows.

and,

Therefore,

Now, putting values in the above formula as follows.

(convert the volume from milliliter to liter)

Thus, there are 20.24 grams of in the solution if the molarity is 0.649 M.
