What does mole a mole represent?

Answer 1

A very large, specific number of items

Answer 2

A very good and an interesting question.

Mole usually termed as gram mole in chemistry.

Mole is the quantity of substance which has 6.023 x 1023 atoms or molecules or ions as the case may be.

Let us take Sodium as an example. Its Atomic Mass is found be 23. (of course the unit hidden is amu) If we have 23 g of sodium then that will be 1 g mol of sodium.

In case of Phosphorous, its Atomic Mass is 31. (amu) If we have 31 g of phosphorous then it will be 1 g mol of phosphorous.

Now oxygen gas. That is O2. The atomic mass of oxygen is 16. So oxygen molecule will have 32 as molecular mass. Thus 32 g of oxygen will be known to be 1 g mol of oxygen gas.

Say carbon di oxide. Its molecular mass is (12+32) 44(amu). So 44 g of carbon di oxide is known as 1 g mol of carbon di oxide.

The beauty is, all these moles will have the same number of atoms or molecules in it. That value is 6.023 x 1023 per gram. This is called as Avogadro's number.

Answer 4

A mole in chemistry represents the amount of a substance that contains Avogadro's number of particles, which is approximately 6.022 x 10^23. This unit is used to measure the quantity of atoms, molecules, or ions in a sample.
