Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

The number of ions of are and number of ions of are .

Explanation:

Potassium sulfide, is an ionic compound. The dissociation of this compound in water will yield:

By Stoichiometry,

One mole of potassium sulfide dissociates into 2 moles of potassium ions and 1 mole of sulfide ion.

According to mole concept:

1 mole of an ionic compound contains number of ions.

So, 2.5 moles of will contain number of ions and number of ions.

Hence, the number of ions of are and number of ions of are .

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
