Because 1 mole is equal to 6.02 x 10^23 . (According to Avogardo . The number of particles in one mole of a substance)

...**How many molecules are there in 4.0 **molecules.

Use dimensional anaysis , convert numbers of mole into numbers of particle.

4.0 moles CO2 x 6.02 x 10^23 molecules CO2 / 1 mole CO2

(just cancel the moles of 4.0 moles CO2 to 1 mole CO2 )

(multiply 4.0 moles CO2 to 6.02 x 10^23 molecules CO2)

and you'll get ---->>> 2.41 x 10 ^24 Molecules CO2
