If 4.5 x 10^-3 moles of MgF2 form a saturated 1 L aqueous solution then whats Ksp for MgF2 at this temperature

Answer 1

4x(4.5)^3x10^-9 = 3.645 x 10^-7

Answer 2

the respond must be 5.a million × 10^–9. Al(OH)3 provides out Al3+ and 3OH- by way of fact Al3+ yields the comparable no. of mole as Al(OH)3, and 3 moles of OH- ions, so enable's make the concentration of Al3+ be X, and OH- be 3X^3 X x 3X^3 = 27X^4 = a million.8 x 10^-32 X = 5.08 x 10^-9 the concentration of Al3+ is 5.08 x 10^-9 by way of fact 2 sig.fig. is used, the respond 5.a million x 10^-9 be taken! i'm hoping this enables.
