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.
What else can I help you with?
How many cations are in K2s?
There are two cations in K2S. Potassium (K) has a +1 charge, so there are two potassium (K) cations in the compound K2S.
What is the percent composition of k2S?
There is no such compound as k2S. But the % composition of K2S (potassium sulfide) is as follows:2 K = 2 x 39 = 78S = 32Total mass = 78 + 32 = 110 g%K = 78/110 (x100) = 70.9 % K%S = 32/110 (x100) = 29.1 % S
How many moles are in 3.3 moles of K2S?
3.3 moles of K2S 3.3 moles of S-2 6.6 moles of K+1
Is k2s an ionic or covalent bond?
K2S or potassium sulfide is an ionic compound.
Is K2S an ironic bond?
No, K2S is not an ironic bond. K2S represents a chemical bond between a potassium (K) atom and a sulfur (S) atom, where they share electrons to form a stable compound. Irony refers to situations where the outcome is different from what is expected.
What is the concentration of in 0.15 of M of K2S?
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.
