Answer:

26%

Explanation:

The percent mass of potassium chloride in a solution is to be considered as the 26%.

Calculation of the percent mass:

Since

mass percent = (mass of solute / total mass of solution ) *100 %

Also,

mass of potassium chloride =25.00g

volume of water= 70.00 ml

Now

mass of solution = mass of solute + mass of solvent

= 25.00 + 70.0

= 95g

Now

mass percent = (mass of solute / total mass of solution ) * 100 %

= (25/95) * 100

= 26.31%

= 26%

Hence, The percent mass of potassium chloride in a solution is to be considered as the 26%.
