A solid sample contains unknown amounts of potassium and magnesium chloride and moisture. 1.193 g of the sample is dissolved in water and the solution is diluted to 250.00 mL. 25.0 mL of the sample is allowed to pass through an H + -saturated cation exchanger, the eluate consuming 22.03 mL of a 0.100 M NaOH solution. The moisture content of the sample was determined to be 5.22%. Calculate the % by weight of potassium and magnesium chloride in the sample.
