The following questions are about one mole of sulphuric acid {H_{2}SO_{4}}?

- FIND THE NUMBER OF GRAM ATOMS OF HYDROGEN IN IT?
- HOW MANY ATOMS OF HYDROGEN DOES IT HAVE?
- HOW MANY ATOMS [IN GRAMS] OF HYDROGEN ARE PRESENT FOR EVERY GRAM ATOM OF OXYGEN IN IT?
- CALCULATE THE NUMBER OF ATOMS IN H
_{2}SO_{4?}

- Number of H atoms in 1 mole of H
_{2}SO_{4}=2 mole.

Number of gram atoms = number of moles of H atoms in 1 mole H_{2}SO_{4} = 2.

- Number of H atoms in 1 mole of H
_{2}SO_{4}= 6.023 x10^{23}x 2 = 12.046 x10^{23}

There are 2 H atoms present with 4 O atoms.

i.e.. 4 O atoms = 2 H atoms

1 O atom = 2/4 =0.5 H atom.

There is 0.5 H are present for every O atom.

- Number of H atoms in 1 mole H2SO4 = 2 x 6.023*10
^{23}=12.046 x10^{23} - Number of O atoms in 1 mole H2SO4 = 4x 6.092*10
^{23}=24.046 x10^{23} - Number of S atoms in 1 mole H2SO4 = 6.022*10
^{2}
