Hydrogen??????????????????????
The answer is always O molecule
When the compound PbI₂ dissolves, it dissociates as follows;
PbI₂ --> Pb²⁺ + 2I⁻
Molar solubility is the number of moles dissolved in 1 L of solution
A saturated solution is when the maximum amount of solute is dissolved in the solution.
Molar solubility of Iodide when solution is saturated is 2.7 x 10⁻³ mol/L, then solubility of Pb²⁺ is (2.7 x 10⁻³ mol/L) / 2 = 1.35 x 10⁻³ mol/L
ksp is the solubility product constant that can be calculated as follows;
ksp = [Pb²⁺][I⁻]
ksp = (1.35 x 10⁻³ mol/L) x (2.7 x 10⁻³ mol/L)²
= 1.35 x 10⁻³ x 7.29 x 10⁻⁶
= 9.8 x 10⁻⁹
Answer:
7.348×10∧7 mg
Explanation:
Given data:
weight in pound= 162 lbs
weight in mg=?
we know that one pound is equal to 453.6 g and 453592.37 mg.
Solution:
mass (mg)= mass (lbs) × 453592.37 mg
mass (mg)= 162× 453592.37
mass(mg)= 73481963.94
or
mass= 7.348×10∧7 mg
Answer:
