Calculate the molecular weight of a compound by inputting its chemical formula
Molecular Weight:g/mol
* Please use uppercase letters for the element symbols in the molecular formula.
Na2SO4
na2so4
Enter a commonly written chemical formula, as shown in the following example:
- H2O
- Na2SO4
- Fe3[Fe(CN)6]2
- Fe3(Fe(CN)6)2
Structured formulas also allow:
- CH2=C(CH3)2
- HOOC-CH2-C(OH)(COOH)-CH2-COOH
- H3C-(CH2)7-CH=CH-(CH2)7-COOH
Symbols can be separated by spaces:
Na2 S O4 or Na 2 S O 4 are treated in the same way.
The formula contains a point showing monohydrate or other adducts.
such as CaSO4 1/2H2O.To enter use the format CaSO4(H2O)1/2, CaSO4(H2O)0.5, or CaSO4(H2O).5
Do not enter a whole number and a fraction to form a number, such as 1 1/2 (it will be 11/2 instead).Use 3/2 or 1.5 instead.
