How many sulfur dioxide molecules are in 2.8 moles of sulfur dioxide

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:



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

Have a nice day!
