A solution contains 4.60 g KCl in 179 mL of solution. The density of the KCl solution is 1.11 g/mL
What is the percent (m/m) for the potassium chloride solution?
What is the molarity, M, for the potassium chloride solution? need help pls

  • chem - ,

    mass soln = volume x density
    %m/m = [g KCl/(g KCl + g solvent)]*100 =

    M = mols/L soln.
    mols = grams/molar mass. volume soln = 0.179L
