Answer:
1.Molecules are made of atoms. So different molecules can have different (or same) number of atoms they are made of.Different atoms are made of different number of protons of neutrons in the nucleus (also electrons around the nucleus but they are very small even compared to atom and don’t add up for volume or mass) therefore their radius and mass are different.
2.Chromatography works because of differences in the properties of molecules in materials.some molecules differ in shape and size. These differences in molecular properties allow scientists to separate compounds into individual molecules using chromatography.
