Akno3 solution is made using 84.4 g of kno3 and diluting to a total solution volume of 1.50 l. calculate the mass percent of the solution. (assume a density of 1.05 g/ml for the solution.)

5.35 g % by mass

Explanation:

Mass percent of the solution means the mass of solute in 100 g  of solution.

84.4 g, the grams of solute are in a certain mass of solution.

Let's determine that mass, with solution density.

Solution density = solution mass / solution volume

1.05 g/mL = solution mass / 1.50L

solution mass = 1500mL . 1.05g/mL → 1575 g

Then, we have to make a rule of three:

1575 grams of solution contain 84.4 grams of solute

100 g of solution will contain (100 . 84.4)/ 1575 = 5.35 g
