Instructions for use:

Enter a chemical formula in the way it is usually written, as shown in the following examples:
H2O
Na2SO4
Ca3(PO4)2
Fe3[Fe(CN)6]2 or Fe3(Fe(CN)6)2

Simplified structure formulas are also allowed:
CH2=C(CH3)2
HOOC-CH2-C(OH)(COOH)-CH2-COOH
H3C-(CH2)7-CH=CH-(CH2)7-COOH, etc.

Symbols can be separated by blanks:
Na2 S O4 or Na 2 S O 4 is processed in the same way as Na2SO4.

Formulas containing a dot indicating a hydrate or other adduct, like CaSO4 · 1/2H2O, have
to be entered using the format CaSO4(H2O)1/2, CaSO4(H2O)0.5, or CaSO4(H2O).5
since the program regards any dot as a decimal point.

Do not enter numbers composed of an integer and a fraction, like 1 1/2 (will be read as 11/2).
Use 3/2 or 1.5 instead.
