As we know that 1 mole of any atom= 6.022*10^23 atoms
Or we can say that 6.022*10^23 atoms have mass=1 mol=atomic mass of
that element.
that element.
Now mass of atom= 6.642 *10^-23g
Mass of 6.022*10^23 atoms = (6.022*10^23)*( 6.642 *10^-23g)
= 39.998124= 40u

From 1 mole of any atom= 6.022*10^23 particles
Or, on the other hand we can state that 6.022*10^23 iotas have mass=1 mol=atomic mass of
that component.
Presently mass of atom= 6.642 *10^-23g
Mass of 6.022*10^23 molecules = (6.022*10^23)*( 6.642 *10^-23g)
= 39.998124= 40u
