The following questions are about one mole of sulphuric acid {H2SO4}?
- 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 H2SO4?
- Number of H atoms in 1 mole of H2SO4=2 mole.
Number of gram atoms = number of moles of H atoms in 1 mole H2SO4 = 2.
- Number of H atoms in 1 mole of H2SO4 = 6.023 x1023 x 2 = 12.046 x1023
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*1023=12.046 x1023
- Number of O atoms in 1 mole H2SO4 = 4x 6.092*1023=24.046 x1023
- Number of S atoms in 1 mole H2SO4 = 6.022*102
