Expert Answer:

Molar mass of HNO3 = 63 g

first lets calculate for H

1 mole of HNO3 contains 1 mole of H

63g of HNO3 = 6.023 x 1023 atoms of H

6.3g of HNO3 = 6.023 x 1022 atoms of H

 

For N,

1 mole of HNO3 = 1 mole of N

63g of HNO3 = 6.023 x 1023 atoms of N

6.3g of HNO3 = 6.023 x 1022 atoms of N

 

For O,

1 mole of HNO3 = 3 mole of O

63g of HNO3 = 3 x  6.023 x 1023 atoms of O

6.3g of HNO3 =18.069 x 1022 atoms of O
