PPT of subtopic 1.2 The mole concept

PPT of subtopic 1.2 The mole concept has following keywords:

Mole, Avogadro’s Number,Molar Mass,Relative Atomic Mass,Relative Molecular Mass,Empirical Formula,Molecular Formula

This PPT of subtopic 1.2 The mole concept aligns with the IB Diploma Chemistry Guide. It covers the past paper questions on this subtopic.

Objectives: This Page enables the students to apply their learning to calculate the molar masses of chemical species like atoms, molecules and ions. They can calculate the amount of reactants and products in moles and the mass in grams. They can determine the empirical formula and molecular formula from the percentage abundance of the constituent elements. The students can calculate moles, molar mass and mass of a substance.

Guidance: The Mole is a quantity while mol is it’s unit. Often students remain confused about the difference.
