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
