What is the formula for mole mass?
What is the formula to find molar mass? The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol).To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

Molecular mass calculator
This tool allows calculating the theoretical isotopic distribution and monoisotopic mass from a Molecular Formula. It is possible to indicate predefined groups, chemical modification of amino acids, specify a given isotope, and modify the isotopic abundance. You can draw the structure or edit directly the molecular formula.
Molecular formula from monoisotopic mass calculator
This tool allows finding possible molecular formula for a measured monoisotopic mass. Just remember that the monoisotopic mass is not always neither the most abundant peak of the isotopic distribution nor the one with the lowest mass.
Advanced molecular formula calculator
This tool allows to find possible molecular formula based on a molecular formula range like the tool 2. As in tool 2, any atom can be specified from the “Atom range selector” table. The main difference is that this atom range selector assists in the selection of the elements, the following information are displayed for each element.
