Use the ICE table approach as solution:
PbSO₄ --> Pb²⁺ + SO₄²⁻
I - 0 0
C - +s +s
E - s s
Ksp = [Pb²⁺][SO₄²⁻]
1.82×10⁻⁸ = s²
Solving for s,
s = <em>1.35×10⁻⁴ M</em>
I THINK that that is true. It's just weathering the rock down not change composition. Lemme know if you get it right please! (:
I believe it would be 1.660539040 × 10−24 gram.
