We need to first find the molarity of Ba(OH₂) solution.
A mass of 3.24 mg is dissolved in 1 L solution.
Ba(OH)₂ moles dissolved - 3.24 x 10⁻³ g/171.3 g/mol = 1.90 x 10⁻⁵ mol
dissociaton of Ba(OH)₂ is as follows;
Ba(OH)₂ --> Ba²⁺ + 2OH⁻
1 mol of Ba(OH)₂ dissociates to form 2OH⁻ ions.
Therefore [OH⁻] = (1.90 x 10⁻⁵)x2 = 3.8 x 10⁻⁵ M
pOH = -log[OH⁻]
pOH = -log (3.8 x 10⁻⁵)
pOH = 4.42
pH + pOH = 14
therefore pH = 14 - 4.42
pH = 9.58

A conservationist is someone who advocates and champions the cause to protect the environment and use earth's resource in a sustainable way.
One of the interesting perks of being a conservationist is the ability to preserve pristine nature.
- This aspect would most fascinate me.
- The joy of having to enact laws and policies that would preserve very vital aspect of the ecosystem would such a great delight.
- Also, having to champion the cause of indigenous people in whose voices are not often disseminated is a good catch
