Atoms & Molecules,
We have,
0.25 mole of hydrogen.
Have to find the no. of atoms present in 0.25 mole.
Now 1 mole of H2 has 6.023 × 10²³ molecules [In some books there is written 1 mole = 6.022 × 10²³ atoms/molecules but I'm using this]
So 1 mole of H2 will have 2 × 6.023 × 10²³ atoms [As 1 molecule of hydrogen has 2 atoms]
Therefore 0.25 mole of H2 will have 2 × 6.023 × 10²³× 0.25 atoms
= 2 × 6.023 × 10²³× 25/100 atoms
= 2 × 6.023 × 10²³× 1/4 atoms
= 6.023 × 10²³× 1/2 atoms
= 3.0115 × 10²³ atoms
That's it
Hope it helped (●´ϖ`●)
