Hello!

To solve this question we are going to use the Avogadro's Number, which tells us how many molecules of a given substance are in a mole. The Avogadro's number is 6,02*10²³ molecules/mol, and we are going to use this value in the following conversion factor:


2,8 moles SO_2* (6,02*10^(23) molecules)/(1 mol SO_2)=1,69 *10^(24) moleculesSO_2

So, there are 1,69*10²⁴ molecules of SO₂ in 2,8 moles.

Have a nice day!
