Answer:
of potassium chloride is required.
Explanation:
Given that,
the mass percentage of solute per mass of the solution is %
We have to figure out the mass of the solute.
(mass of the solvent)
We know that the mass of the solution is equal to the sum of the mass of the solute and the mass of the solvent.
i.e.
Now,
%
%
Hence, potassium chloride is required.
