Answer:

53 g of Na2CO3 Contain = 53106=12 mol.

No of atoms of Na = 12×2×6.022×1023= 6.022×1023.

No of atoms of C = 12×6.022×1023.

No of atoms of O = 12×3×6.022×1023= 9.033×1023.

Answer:

Molecular mass of Na2CO3 = ( 2 × 23 ) + 12 + (3 × 16) = 46 + 12 + 48 = 106  

Given mass of Na2CO3 = 53 g

106 g of Na2CO3 Contain = 1 mol

53 g of Na2CO3 Contain = 53106=12 mol  

 

No of atoms of Na = 12×2×6.022×1023= 6.022×1023

No of atoms of C = 12×6.022×1023

= 3.011×1023

No of atoms of O = 12×3×6.022×1023= 9.033×1023
