Answer 1

For this problem, we have to use Avogadro's number which is 6.022 x 10^(23) /mol. This number is telling us that there are 6.022 x 10^(23) atoms in 1 mole of a certain compound/element. The conversion would be:

`0.30molesSO_2\cdot\frac{6.022\cdot10^(23)atoms}{1\text{ mol}}=1.8\cdot10^(23)atoms.`

The answer is that there are 1.8 x 10 ^(23) atoms of SO2 in 0.30 moles.
