answer 12.49
![12.46.Explain why molality is used for boiling-point
elevation and freezing-point depression calculations
and molarity is used in osmotic pressure calculations.
12.48 Describe how you would use freezing-point
depression and osmotic pressure measurements to
determine the molar mass of a compound. Why are
boiling-point elevation and vapor-pressure lowering
normally not used for this purpose?
12.49.Explain why it is essential that fl uids used in
intravenous injections have approximately the same
osmotic pressure as blood.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff80a15f6-d366-4392-bd8f-d290fb6acf54%2Fd05fcd84-0806-40af-bd8c-94a9357bafc3%2Flj8y9i_processed.jpeg&w=3840&q=75)
