In this video, Chemistry Tutor goes more in depth about the topic of Mole Concept.

This is part 2 out of 2 of the Mole Concept topic.

First formula is: Number of moles=Mass / Mr (Mr refers to the molecular mass of an element or compound)

Second formula is: Number of moles of gas = Volume/ 24 dm3 or Number of moles of gas = Volume / 24 000 cm3

This formula can only be used when gaseous elements are involved.
