How do you do the mole concept?
The number of moles in a given sample of an element/compound can be calculated by dividing the total mass of the sample by the molar mass of the element/compound, as described by the following formula. Therefore, the mass of one mole of an element will be equal to its atomic mass in grams.
What is a mole project chemistry?
The Mole Project was an opportunity for students to demonstrate their understanding of chemical moles and dimensional analysis. A mole is a number used in chemistry to represent very large numbers of small things like atoms or molecules.
Why is mole concept so difficult?
(1993) it was found that the operative introduction of the ‘mole’ concept deprives it of a chemical meaning and makes ‘mole’ difficult to understand by pupils with no previous ideas about this concept.
How do you explain moles to students?

Explain that a mole, or 6.02 x 1023, is just a convenient number for talking about atoms. Ask the students why they think it is that we don’t talk about atoms and molecules in terms of dozens or scores.
