Consider the three types of percent composition of a solution. (a) What are the names of these three types of percent compositions? (b) Which term is missing from all three types of percent compositions: solvent, solute, or solution? (c) Give the mathematical definition of each type of percent composition.

There are three different ways to express the percent composition of a solution. They are: 1. Mass percent 2. Volume percent 3. Mass/volume percent

Out of the three terms (solvent, solute, and solution), the term "solvent" is missing from all three types of percent compositions. The percent compositions typically involve the solute's amount concerning the total solution.

Here are the mathematical definitions for each type of percent composition: 1. Mass percent: The mass percent composition is expressed as the mass of the solute (in grams) divided by the total mass of the solution (in grams) multiplied by 100. Mathematically, it can be written as: Mass percent = \(\frac{mass_{solute}}{mass_{solution}} × 100\) 2. Volume percent: The volume percent composition is calculated as the volume of the solute (in milliliters) divided by the total volume of the solution (in milliliters) and then multiplied by 100. Mathematically, it can be written as: Volume percent = \(\frac{volume_{solute}}{volume_{solution}} × 100\) 3. Mass/volume percent: The mass/volume percent composition is expressed as the mass of the solute (in grams) divided by the total volume of the solution (in milliliters) multiplied by 100. Mathematically, it can be written as: Mass/volume percent = \(\frac{mass_{solute}}{volume_{solution}} × 100\)
