What is the difference between a 1 M solution and a 1 m solution?

Short Answer

Expert verified

1M solution contains 1mole of solute for every 1L solution whereas 1m solution contains 1mole of solute for every kg of solvent.

Step by step solution

01

Definition

Molarity isthe calculation of the number of solutes that are present in a litre of a solution.

The total number of moles of a solute that are present in one kilogram of a solvent is known as its molality.

02

Explanation

The key difference between a 1.0 molar solution and a 1molal solution is that a 1.0 molar solution has onemoleofsolutedissolved within the solution whereas a 1molal solution has one mole of solutes dissolved in one kilogram of the solution. Furthermore, the unit of measurement of 1.0 molar solution is mole/L while that of 1molal solution is mole/kg.
