Let x be mol/l of Sn(OH)2 that dissolve
Therefore, this will give x mol/l Sn2+ and 2x mol/l OH-
Ksp= (Sn2+)(OH-)^2
= (x)(2x)^2
= 4x^3
4x^3 = 5.45 × 10^-27
x = 1.11 × 10^-9
x = molar solubility = 1.11×10^-9 M
<span>D. The temperature of a gas varies directly with pressure.
That is because temperature has an SI unit of Kelvin, and also deals directly with pressure. </span>
