The Molecular Calculator is designed to calculate the molecular and reciprocal weight of any chemical formula.

usage:
* Enter a chemical formula the standard way.
* Symbols can be seperated by blanks.
* Simplified structures are also allowed.
* Formulas cointaining a multiplication (such as hydrates) should be entered without the dot.
* Numbers composed by an integer and a fraction (like 1 1/2) should be replaced by a fraction (3/2) or using decimal notation (1.5).
* The chemical formulas are case sensetive.

Examples:
* H2O
* Ns2SO4
* Fe3[Fe(CN)6]2
* HOOC-CH2-C(OH)(COOH)-CH2-COOH
* H3C-(CH2)7-CH
