While reading the stoichiometry section in TBR, I found a phrase that wasn't entirely clear. It states,
How exactly is the quantity that doesn't change with temperature used in determining the temperature change? Also does the word concentration used in the later sentence refer to the concentration mentioned in the first sentence, or is it talking about the conentration in a traditinoal sense (#moles/volume). I know I am missing something here. Does anyone have an idea as to what the book was trying to allude?Molality is the concentration of a fluid solution defined as the moles of a solute per kilogram of solvent. The molality of a solution does not change with temperature, so it is often used to determine a change in the solution's temperature when the change depends on concentration. Notable examples of this include boiling-point elevation and freezing-point depression.
