Solution:
Concept:
- Molarity:
- It is defined as the moles of a solute per litres of a solution.
- It is also known as the molar concentration of a solution.
- Molality:
- It is defined as the number of moles of solute per kilogram of solvent.
- Mole fraction:
- It is the ratio of moles of a component with the total moles of solute and solvent.
- Mass%:
- It is the percentage of the mass of solute or solvent w.r.t total mass of solution.
Explanation:
- Molarity depends on the volume of the solution.
- And volume is directly proportional to temperature.
- And when we increase the temperature the volume will increase.
- So the increase in volume leads to a decrease in Molarity as Molarity is inversely proportional to the volume of solution.
