Select the statements that are TRUE about molality. Molality (m): Moles of solute per kilograms of solvent. moles of solute Molality= kilograms of solvent Molality is temperature dependent. Molality can be used for freezing point depres- sion problems as well as boiling point elevation problems. Molality is a typo, the word is supposed to be "molarity". Molality is used for Raoult's Law problems.

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.
