Expert Answer:
Given:
1 g of carbon contains x atoms ......... (1)
1 mole of carbon = gram molecular mass of carbon = 12 gms
i.e., 12 gms of Carbon = 1 mole
...........(2)
From (1) and (2) we get,
As given we have to find out the number of atoms in 1 gm of Mg,
1 mole of Mg = 24 gm ..... ( mass no. of Mg = 24)
...... (3)
In order to find the number of atoms of Mg in 1 g, lets solve (2) and (3)
