The order of solubilities is AgNO₂ > AgCl > Ag₂O > AgSCN > AgBr > AgI
Unless you look up the solubilities, I think you must use the Kₛₚ values to calculate solubilities.
For the AgX compounds
AgX ⇌ Ag⁺ +X⁻
Kₛₚ = s × s =s²
s = √Kₛₚ
For Ag₂O, the equation is
Ag₂O + H₂O ⇌ 2Ag⁺ + 2OH⁻
Kₛₚ = 2s × 2s = 4s²
s = ½√Kₛₚ
I found the following values and calculated the solubilities.
Compound Kₛₚ s(mol·L⁻¹)
AgCl 1.77×10⁻¹⁰ 1.33×10⁻⁵
AgBr 5.35×10⁻¹³ 7.31×10⁻⁷
AgI 8.52×10⁻¹⁷ 9.23×10⁻⁹
AgNO₂ 6.0×10⁻⁴ 2.5×10⁻²
AgSCN 1.03×10⁻¹² 1.01×10⁻⁶
Ag₂O 1.52×10⁻⁸ 6.16×10⁻⁵
AgNO₂ > AgCl > Ag₂O > AgSCN > AgBr > AgI
