Solution Example: Make 2 g/100mL of NaCl solution with 1 L water Water (properties). The density of resulting solution is considered to be equal to that of water, statement holding especially for dilute solutions, so the density information is not required. Solution In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances. The term aqueous solution is when one of the solvents is water. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. The mixing process of a solution happens at a scale where the effects
Mass fraction (chemistry) Mass fraction (chemistry) In chemistry, the mass fraction formula_1 is the ratio of one substance with mass formula_2 to the mass of the total mixture formula_3, defined as The symbol formula_5 is also used to denote mass fraction. The sum of all the mass fractions is equal to 1: Mass fraction can also be expressed, with a denominator of 100, as percentage by mass (in commercial contexts often called "percentage by weight", abbreviated "wt%"; see mass versus weight). It is one way of expressing the composition of a mixture in a dimensionless size; mole fraction (percentage by moles, mol%) and
