Calculate the mass of dissolved nitrogen at 25°C in an aquarium containing 64.7 L of water. Assume the total pressure is 97.8 kPa and the mole fraction of nitrogen in air is 0.78. Recall that the partial pressure of a gas in a gas mixture can be determined from the full pressure and its mole fraction (Henry's law, Dalton's law).

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.
