How to know the number of moles of an element in the periodic table?
Asked by reenabhartintpc001 | 12 Mar, 2018, 07:38: PM
Expert Answer
Gram atomic mass of an element= 1 mole of element.
We can find the molecular weight from the periodic table.
A mole is a collection of 6.022 × 1023 particles.
A mole is defined as the amount of a substance containing elementary particles like atoms, molecules or ions in 12 gram of carbon-12 (12C).
1 mole of atoms = 6·023 × 1023 atoms = Avogadro’s number
