Putting in a molecular formula of any type such as K2Cr2O7, CH3CH2COOH, KFe[Fe(CN)6]3, or Na2B4O7.10H20 will result in the molar mass and mass analyses being calculated when the button is pressed. Please make sure that the formula has no more than two different bracket levels open at the same time, and that molecule of crystalization is placed last.

Formular Weight = g/mol
1.000 g = mmol
1 mmole = g
