Answer 1

3 x 10²⁴ molecules

Step-by-step explanation:

A mole is just a name that we use to substitute a number, just like a dozen means 12, a mole means 6.022 x 10²³. This gives us the unit conversion of 6.022 x 10²³ molecules SO₂/1 mol SO₂.

`5molSO2*(6.022 x 10^2^3molecules)/(1mol SO2) = 3.011 x 10^2^4moleculesSO2`

Round to the lowest number of significant figures to get 3 x 10²⁴ molecules SO₂
