Hi Amigo !

Yes, I'll help 
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
