The Molar Mass of Deuteron is 2.01355321 kilograms per mole.  This constant, `M_d`, defines the molar mass of deuteron, the nucleus of Deuterium.  The molar mass of Deuteron is expressed in kilograms / mole (kg/mol).  However, this can be automatically converted to compatible units via the pull-down menu.

Notes

Deuterium (symbol D or 2H, also known as heavy hydrogen) is one of two stable isotopes of hydrogen. It has a natural abundance in Earth's oceans of about one atom in 6,420 of hydrogen.

This constant, `M_d`, is specified with a standard uncertainty (standard deviation) of: 0.000000000077 E-3 kg/mol
