Estimate the solubility of silver cyanide?

Question

in (a) moles per liter and (b) grams per liter in pure water at 25 degrees Celsius.

AgCN(s) Ag+(aq) + CN—(aq)

Answer 1

Ksp =1.2 x 10^-16 = [Ag+][CN-] = (x)(x)

x = molar solubility = 1.1 x 10^-8 M

1.1 x 10^-8 mol/L x 133.88777 g/mol =1.5 x 10^-6 g/L
