| 305773126 | molarity | moles of solute per volume of solution in liters | |
| 305773127 | mass percent | the percent by mass of a component of a mixture or of a given element in a compound | |
| 305773128 | mole fraction | the ratio of the number of moles of a given component in a mixture to the total number of moles in the mixture | |
| 305773129 | molality | number of moles of solute per kilogram of solvent in a solution | |
| 305773130 | enthalpy (heat) of solution | enthalpy change associated with the formation of the solution | |
| 305773131 | enthalpy (heat) of hydration | the enthalpy from H2 (expanding solvent) and H3 (the solvent-solute interaction). It represents the enthapy change associated with the dispersal of a gaseous solute in water. | |

| 305773133 | thermal pollution | oxygen-depleting effect on lakes and rivers of using water for industrial cooling and returning it to its natural source at a higher temperature | |
| 305773134 | Raoult's Law | the vapor pressure of a solution is directly proportional to the mole fraction of solvent present | |
| 305773135 | ideal solution | solution whose vapor pressure is directly proportional to the mole fraction of solvent present | |
| 305773136 | colligative properties | properties of a solution that depend only on the number, an dnot on the identity of the solute particles | |
| 305773137 | molal boiling-point elevation constant | constant characteristic of a solvent that gives the change in boiling point as a function of solution molality; used in molecular weight determination | |
| 305773138 | molal freezing-point depression constant | constant characteristic of a solvent that gives the change in freezing point as a function of the solution molality; used in molecular weight determination | |
