Document Summary

Nucleus contains protons and neutrons and this is where mass comes from. Mass spectrometer- height to the peaks show relative mass, how much of each different mass. The lines show the different products formed when something forms. Masses are a weighted average of all the different isotopes. Molecular is the a(cid:373)ou(cid:374)t of each ele(cid:373)e(cid:374)t (cid:374)eeded to actually (cid:373)ake the co(cid:373)pou(cid:374)d. it s (cid:374)ot the lowest integer value. 31 g phosphorus react with oxygen gas to form 71 g phosphorus oxide.
