Answer:
Explanation:
You can convert the <em>density</em> into <em>atomic density</em> using the <em>atomic weight </em>and Avogadro's number
A dimensional analysis is very helpful:
Follow the chain: g cancels with g, mol cancels with mol; at the end, what remains is atoms/cm³, which is what you want.
Use that with your data:
of the compound is found to be 5.04 ×
.
Solubility :Solubility can be define as the amount of a substance that dissolves or mixes in a given amount of solvent at specific conditions.
Solubility equilibrium
Ksp =
Ksp = solubility product constant
A+ = cation in an aquious solution
B- = anion in an aqueous solution
a, b = relative concentrations of a and b
Given,
Solubility = s = 3.60 × g/L
molar mass = 288 g/ mol
∴ s= 3.60 × g/L ÷ 288 g/ mol = 1.25 ×
mol/ L
Reaction:
MX3 ⇄ M + 3X
s 3s

= solubility product
∴ =
∴ = 3
∴ = 3 × (3.60 ×
∴ = 503.8848 ×
= 5.04 ×
