Question

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 H₂SO_4?

Answer 1

• 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
