Answer:
The concentration of is
The number of ion is
Explanation:
Generally the solubility product constant of HgS(s) is
This solubility product constant is mathematically represented as
Since the HgS is saturated it implies that the concentration of sulfur ion is the same as that of mercury ion s
=>
=>
substituting values
=>
From above mole of is equal to 1 L
Then x mole of will be equal to 1000 L
Therefore
=>
Now the number of ions are in 1000 L of the solution is mathematically represented as
Where is the avogadro's constant which has a value of
Substituting value
<h2><u>Answer</u> :</h2>
The most appropriate option is :
Since, they are the most abundant elements found in Earth's Crust.
The answer to this would be 22 mL
