Question

A composition of a solution can be expressed in several different ways. Find of the most common concentration units a defined as follows. mass % = mass of component/total mass of solutions Times 100 % molarity (M) = moles of solute/of solution molality (m) = moles of swolute/mass of solvent (kg) Calculate the mass percent of KCl in the solution. Express you answer with the appropriate units. Calculate the molefraction of the spacing KCl in the solution Express the concentration numerically as a mole fraction in decimal form.

Explanation / Answer

It is 37 gm because mass of solute in solution does not change on dissolving in solvent.
