If you have 2 moles of K+ for every mole of K2S and Molarity (M) is Moles per Liter. Then you know that you have .30 M of K2S. The way that you do that is setting up a series of conversion factors like so:(.15moles k2s/liter) x (2 moles of K/ 1 mole of K2S) = .30 moles k/ liter.The moles of K2S cancel out and you are left with moles of K per liter.

33 grams aluminum (1 mole Al/26.98 grams) = 1.2 moles of aluminum ================

Formula for potassium sulfide is K2S.

K2S + 2HCl --> 2KCl + H2S
