请教一道关于化学平衡常数的问题.
What is the minimum number of moles of
PbSO4 that must be used to prepare 1 liter of
saturated PbSO4 solution at 25°C?(Ksp at
25°C for PbSO4 = 1×10−8 )
(A) 1×10−16mol
(B) 1×10−8mol
(C) 1×10−4mol
(D) 1×10−2mol
(E) 1×10−1mol
求最小的所需的物质的量PbSO4制备一升饱和溶液饱和PbSO4溶液(Ksp PbSO4 = 1×10−8 在25°C)

(C) 1×10-4mol
Ksp=[Pb2+][SO42-]=1×10-8
C is just right. If want to see some solid remained in solution, then use D.
