Molarity is a measure of the concentration of a solution expressed as the number of moles of solute per liter of solution.

• Molarity is calculated by dividing the number of moles of solute by the volume of the solution in liters.

• It is denoted by the symbol 'M'.

• Molarity is commonly used in chemistry to express the concentration of a solution.

• For example, a 1 M solution of sodium chloride contains 1 mole of sodium chloride

Molarity is the concentration of a solution in terms of the number of moles of solute per liter of solution, while molality is the concentration of a solution in terms of the number of moles of solute per kilogram of solvent.

• Molarity is denoted by M, while molality is denoted by m.

• Molarity is affected by temperature changes, while molality is not.

• Molarity is used in chemical reactions, while molality is used in colliga...read more

HPLC stands for High Performance Liquid Chromatography. It is a principle used in analytical chemistry to separate, identify, and quantify components in a mixture.

• HPLC uses a liquid mobile phase and a solid stationary phase to separate components based on their interactions with the stationary phase.
