Without doing any detailed calculations (but using a periodic table to give atomic weights), rank the follow- ing samples in order of increasing numbers of atoms: 42 g of NaHCO3, 1.5 mol CO2, 6.0 x 1024 Ne atoms.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.

the answer is symmetrical : )
