I have used the equation of real gas
Explanation:
Let us assume that the value of =
Also at 1500 K, =
Relation between and is as follows.
Putting the given values into the above formula as follows.
Also,
or,
=
=
Thus, we can conclude that the value of is .
When cobalt (II) hydroxide dissolves, it dissociates into the following ions,
Co(OH)₂ --> Co²⁺ + 2OH⁻
molar solubility is the number of moles that are dissolved in 1 L of solution.
If molar solubility of Co(OH)₂ is X, then molar solubility of Co²⁺ is X and molar solubility of OH⁻ is 2X.
the formula for solubility product constant - ksp is as follows;
ksp = [Co²⁺][OH⁻]²
ksp = (X) * (2X)²
ksp = 4X³
ksp = 5.92 x 10⁻¹⁵
4X³ = 5.92 x 10⁻¹⁵
X = 1.14 x 10⁻⁵ M
molar solubility of Co(OH)₂ is 1.14 x 10⁻⁵ M
solubility of compound - 1.14 x 10⁻⁵ mol/L x 93 g/mol = 1.06 x 10⁻³ g/L
Answer:
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
