Write all the formulae related to the mole concept, how to find moles, particles, molecules in a given element.
GeekPH:
When the mass of the substance is given: Use this formula: Number of moles = given mass/ atomic mass
Calculation of number of particles when the mass of the substance is given:
Number of particles =( Avogadro number x given mass)/gram molecular mass
Number of particles =( Avogadro number x given mass)/gram molecular mass
Calculation of mass when number of particles of a substance is given:
Mass of a substance = (gram molecular mass x number of particles)/6.023 x 1023
Mass of a substance = (gram molecular mass x number of particles)/6.023 x 1023
