what volume of water is needed to completely dissolve 4.0 g of Ag2CrO4 (Ksp = 8.0 x 10^-12, MM = 331.8 g/mol)
At equilibrium:
Ag2CrO4 <----> 2 Ag+ + CrO42-
2s s
Ksp = [Ag+]^2[CrO42-]
8*10^-12=(2s)^2*(s)
8*10^-12= 4(s)^3
s = 1.26*10^-4 M
Molar mass of Ag2CrO4 = 331.8 g/mol
Molar mass of Ag2CrO4= 331.8 g/mol
s = 1.26*10^-4 mol/L
To covert it to g/L, multiply it by molar mass
s = 1.26*10^-4 mol/L * 331.8 g/mol
s = 4.18*10^-2 g/L
Now use:
Volume = mass / s
= (4.0 g) / (4.18*10^-2 g/L)
= 95.7 L
Answer: 96 L
