mass is a better measure, since it doesn't depend on the magnitude of the local gravitational field. even better is number of particles (moles) since particles combine in whole-number proportions in chemical reactions.

I will try to explain--
weight is relative. They dont go by the weight of an element because you could have an element that is extremely light (say a gas) and take the same weight of a heavier element (say lead) and you would have a huge difference in the mass or volume of the two substances. Chemists use the mole theory because then you will have an equal number of substance in each sample. Does this make sense?
