A patient requires an IV infusion of an isotonic saline solution containing equal molar amounts of potassium chloride and magnesium chloride. In clinical practice, a saline solution is said to be isotonic if it has the same osmotic pressure as blood plasma (7.74 atm at 36 °C). Give the mass of potassium chloride plus the mass of magnesium chloride in grams that needs to be dissolved in 1.15 L of distilled water to make it isotonic. Assume that the change in volume of the solution after adding the salts can be neglected. Give the answer in grams with 3 or more significant figures.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
