Question

What is the difference between mole,avogadro number and mass?

Answer 1

Answer:

Avogadro's number is a proportion that relates molar mass on an atomic scale to physical mass on a human scale. Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance.

Answer 2

Answer:

The mole allows scientists to calculate the number of elementary entities (usually atoms or molecules ) in a certain mass of a given substance.

Avogadro’s number is an absolute number: there are 6.022 × 1023elementary entities in 1 mole. This can also be written as 6.022 × 1023mol-1.

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.
