same here, I keep misinterpreting what the question is asking from me.
and yes doing AS resits while managing A2 is hard so I'm kinda travelling down the same road as you...
how many past papers have you done tho?

Its pretty easy. You start off by finding the number of moles. (3.06/30.6 =0.1mol)
Then * by avogadro =6*10^22
Now the number of atoms in CO2 is three. 1 Carbon 2 oxygen.
6*10^22 * 3=1.8*10^23 (answer C)
