A company needs 1.50 L of a 0.9% sodium chloride solution. They only have a 2.5% solution.
What is the volume of stock needed to make 1.50 L of 0.9% sodium chloride from a 2.5% stock
solution?
What is the total amount of sodium chloride in grams the final solution
If you have a 1 molar solutions of both potassium chloride and calcium chloride which will have
the greatest concentration of chloride ions. Justify your answer.
