comment How do I write a function that returns the atomic mass given an element's symbol?
@1234. I can supply such a function, but i don't see any use for it. The density of a solid is not related to the atomic mass of its constituent elements in any simple way. For example, Au has a lower atomic mass than Pb, but it is denser.

comment How do I write a function that returns the atomic mass given an element's symbol?
@1234. I'll give a hint. Write a function that takes Fe73B13Si9 as a string and use built-in string and list processing functions to make two lists: {"Fe", "B", "Si"} and {73, 13, 9}. Map atomMass over the 1st list, then do a dot product.
