well Follow me :
Avogadro Number = It is defined as the number of atoms present in one gram of the element or molecules of the substance
@ 1 mole of carbon atom = 12 g
@ 1 mole of carbon- atom = 6.022 X 10²³ atoms of carbon
@ 1 mole of CO2 gas = 22.4 L of CO2 at STP
@ 1 mole of NaCl = 58.5 g of NaCl
@ 1 mole of NaCl = 6.022 X 10²³ formula units of NaCl
@ % of element = No. of parts by mass of element / molar mass X 100
@ Molecular formula = n X empirical formula
@ n = molecular mass /Emperical formula mass
@ Mass of gas = 2 x vapour density
@Molecular mass = 22.4 L at STP
