The value of ksp for silver sulfide, ag2s, is 8.00×10−51. calculate the solubility of ag2s in grams per liter.
Ivanshal [37]
When Ag₂S dissolves, it dissociates as follows;
Ag₂S ---> 2Ag⁺ + S²⁻
First we need to calculate molar solubility which gives the number of moles dissolved in 1 L of solution.
If molar solubility of Ag₂S is y, then molar solubility of Ag²⁺ and S²⁻ is 2y and y respectively.
ksp gives the solubility constant
ksp = [Ag⁺]²[S²⁻]
ksp = [2y]²[y]
4y³ = 8.00 x 10⁻⁵¹ 
y³ = 2 x 10⁻⁵¹
y = 1.26 x 10⁻¹⁷ mol/L
molar mass = 247.8 g/mol
solubility of Ag₂S = 1.26 x 10⁻¹⁷ mol/L x 247.8 g/mol = 3.12 x 10⁻¹⁵ g/L 
Solubility of Ag₂S = 3.12 x 10⁻¹⁵ g/L

Compound AB decomposes into elements A and B by the following reaction: AB →A + B. If you produce 10.00 g of B and 3.00 g of A,
zavuch27 [327]

Answer:

13.00 g

Explanation:

To solve this problem, you need to understand the law of conservation of mass.  This law means that whatever amount you start out with is what you should have at the end.  The amount may be in different forms, but that amount is still there.

If you produced 10.00 g of B and 3.00 g of A, you should have started out with 13.00 g of AB.

10.00 + 3.00 = 13.00
