Question

The number of units, which are used to express concentration of solutions from the following is _________. (Mass percent, Mole, Mole fraction, Molarity, ppm, Molality.)

TestHub · Accepted Answer

Both solute and solvent(solution) terms are involved in the concentration term of solution. Mass percent, mole fraction, molarity, ppm, molality are used for measuring concentration terms. The number of moles is mass to molar mass ratio, it is not a concentration term for a solution.
