Adolph Frank and Nikodem Caro found that Nitrogen could be fixed by using the same calcium carbide produced to make acetylene to form calcium-cyanamide, which could then be divided with water to form ammonia. The molar mass of B is 50.0 g/mol. Ammonia concentrations in streams are rarely high enough to exhibit this odor, but water that has a foul, septic or organic-waste smell may have relatively high concentrations of ammonia.
