Answer to Question #185159 in General Chemistry for hayley samantha farah

Question

Find the mass percent if 6.86 g of KCl are dissolved to make a 250.0 g solution.

Answer 1

Given Data-

Mass of solution = 250.0gm

Mass of solute = 6.86gm

Now,

Mass percent = (mass of solute/mass of solution)×100

Mass percent =(6.86gm/250.0gm)×100

Mass percent =2.74%

Hence the mass percent is 2.74%
