If 1 g of contains x atoms, what will be the number of atoms in 1 g of magnesium? (C=12 u, Mg= 24 u)

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)
