## Question:

Calculate the molality, molarity, and mole fraction of a {eq}\rm 25.4\% {/eq} (by mass) aqueous solution of phosphoric acid {eq}\rm \left (H_3PO_4\right ) {/eq}.

## Concentration of Solution:

Different units of concentration for a solution may involve different variables. For example, molality will require moles of the solute and the mass of the solvent in kilograms while molarity will require moles of the solute and the volume of the solution in liters. On the other hand, the mole fraction requires the moles of the solute and the total moles in the solution.
