Explanation:

Take a look at the attachment below,

Answer 2

What is the molality of the solution?

565 grams = 565.1000

                  =0.565 kg (H20)

molar mass (Potassium Chloride),

mass of Potassium + Mass of Chloride,

39.0983 + 35.453

        =74 5513 g 1 mol

Given - 968 grams (Potassium chloride)

{  (9.68 g KCI)  }

(74.5513 g KCI mol)

0.565 kg H2O

( 0.23 mol / kg ) - about ,

solution =0.23 in KCI

  [0.23] m KCI
