Answer:
Explanation:
In an aqueous solution of potassium sulfate (K₂SO₄), the solute is K₂SO₄ and the solvent is water. The percentage by mass describes the grams of solute there are dissolved per 100 grams of solution. It can be calculated as:
mass percentage = (mass of solute/total mass of solution) x 100%
For example, in an aqueous solution which is 2% by mass of K₂SO₄, there are 2 grams of K₂SO₄ per 100 g of solution.

The answer is
<h2>
</h2>
Explanation:
The pH of a solution can be found by using the formula
where
is the hydrogen ion concentration of the solution
From the question
pH = 8.25
The hydrogen ion concentration of the solution is
<u>Find antilog of both sides</u>
That's
We have the final answer as
