No. of moles = Vol / 22.4
= 5.6 / 22.4
= 0.25 moles
No. Of molecules = Avogadro no * No of moles
6.023 * 1023 * 0.25
=1.50575 *1023
= 5.6 / 22.4
= 0.25 moles
No. Of molecules = Avogadro no * No of moles
6.023 * 1023 * 0.25
=1.50575 *1023

1 mole = 6.67 × 10^23
mole = gw/mm
mole = 5.6/18.04
mole = .3
6.67 × 10^23 × .3
2.001 × 10^23 molecules
