Question

A solution concentration must be expressed in molality when considering boiling-point elevation or freezing-point depression but can be expressed in molarity when consider- ing osmotic pressure. Why?

Accepted Answer

Hello everyone today. We have the following problem differentiate morality and polarity and expressing solution concentration when considering freezing point depression, boiling point elevation and osmotic pressure. Well first let's determine what morality can help us find some modality is used when we calculate freezing point depression and not only that but boiling point elevation. And so why is that? That is because its concentration unit for morality is dependent independent on temperature change. And if we look at polarity, malaria is going to help us with osmotic with oz, ma dick pressure differences. And so why osmotic pressure? That's because osmotic pressure is actually dependent on temperature change mainly because it is measured at constant temperature. So if we look at our answer choices, answer choice. D. Best highlights this, morality must be used when calculating freezing point depression and boiling point elevation while polarity can be used for osmotic pressure calculations. And so with that we've answered the question overall, I hope that this helped and until next time.
