To find the total number of atoms in the sample of CO2, convert from grams to mols to atoms by using the molecular weight of CO2 (12.01 + 2(16) = 44.01 g/mol) and Avogadro's number (6.022x1023 atoms).
33.5g CO2 1 mol CO2 6.022x10^23 atoms CO2
_________ x __________ x _____________________ = total number of atoms in 33.5g CO2
44.01 g CO2 1 mol CO2
I hope this helped!
