A solution was prepared by dissolving 43.0 of in 225 of water.
Calculate the mass percent of in the solution.
Sorry, can't help! Would if i could, really!
of KCl
43 WHAT?
225 WHAT?
43g
225g
mass percent is (mass solute/100 g soln)*100.
You have 43 g KCl/225 g water.
Therefore, the solution has a mass of 225 g water + 43 g KCl = ?? grams.
Substitute into the above and solve for percent.
To calculate the mass percent of a solute in a solution, you need to know the mass of the solute and the mass of the solution.
Given information:
Mass of solute (sodium chloride) = 43.0 g
Mass of solvent (water) = 225 g
To find the mass percent, you need to divide the mass of the solute by the mass of the solution and then multiply by 100 to express the result as a percentage.
Step 1: Calculate the mass of the solution.
Mass of solution = Mass of solute + Mass of solvent
Mass of solution = 43.0 g + 225 g
Mass of solution = 268.0 g
Step 2: Calculate the mass percent.
Mass percent = (Mass of solute / Mass of solution) x 100
Mass percent = (43.0 g / 268.0 g) x 100
Mass percent = 0.1604 x 100
Mass percent = 16.04%
Therefore, the mass percent of sodium chloride in the solution is 16.04%.
