A solution of KCIO3 is prepared using 75 grams of the solute in enough water to make 0.250 liters of solution. The gram-formula mass of KCIO3 is 122 grams per mole.


-- Determine the percent by mass of solute in the solution.

Verified Answer :

Using the mass/volume percentage method for percentages of the solution, you simply divide the grams of solute by the volume of the solution and multiply by 100 to get your percentage.
(75.0g/250mL)•100 = 30.0% solute

The mass percent of the solute present is 99.7%.

What is mass percent?

The term mass percent refers to the ratio of the mass of solute to the mass of the solution multiplied by 100.

We have the following information;

volume of the water = 0.250 liters

Mass of the water = 0.250 g

Mass of the solute = 75 grams

Mas of solute and  solvent = 0.250 g + 75 grams = 75.250 g

Mass percent of the solute = 75 grams /75.250 g * 100 = 99.7%
