Molecular weight diagram
This calc finds the molecular weight of organic compounds based on their empirical formula. The atomic molecular weights are used according to their naturally-occurring isotope ratios, so this calc is not suitable for accurate mass determination in mass spectrometry.

H (hydrogen)
N (nitrogen)
O (oxygen)
S (sulfur)
