Question
Chapter 20, Problem 84A
Interpretation Introduction
Interpretation:
The differences between molarity and molality are to be written.
Concept introduction:
Molality is the amount of solute per kilogram of solvent and Molarity is the amount of solute per litre of solution.
Expert Solution & Answer
Answer to Problem 84A
The molarity of a solution depends on the type of both solute and solvent while the molality depends only on the nature of solvent. The molarity of a fixed solution can change with change in physical conditions, but molality remains same in every condition.
Explanation of Solution
Since the molarity of a solution depends upon the volume of whole solution and not solvent only, the nature of solute is also considered. Also, the dependence of molarity on volume makes it change with changes in pressure or temperature due to volume being dependent on it.
Conclusion
Molarity and molality differ from each other due to their different dependencies and units of measurement.

- 1. For each of the following statements, indicate whether they are true of false. ⚫ the terms primary, secondary and tertiary have different meanings when applied to amines than they do when applied to alcohols. • a tertiary amine is one that is bonded to a tertiary carbon atom (one with three C atoms bonded to it). • simple five-membered heteroaromatic compounds (e.g. pyrrole) are typically more electron rich than benzene. ⚫ simple six-membered heteroaromatic compounds (e.g. pyridine) are typically more electron rich than benzene. • pyrrole is very weakly basic because protonation anywhere on the ring disrupts the aromaticity. • thiophene is more reactive than benzene toward electrophilic aromatic substitution. • pyridine is more reactive than nitrobenzene toward electrophilic aromatic substitution. • the lone pair on the nitrogen atom of pyridine is part of the pi system.arrow_forwardThe following reactions are NOT ordered in the way in which they occur.
