Element Manganese - Mn

Manganese is a transition metal with a molar mass of 54.94g/mol. Manganese is considered critical for human health, and plays important roles in development, metabolism, and the antioxidant system. That said, excessive manganese intake is associated with manganism, a neurodegenerative disorder that causes dopaminergic neuronal death and parkinsonian-like symptoms. ›› Manganese molecular weight. Molar mass of Mn = 54.938049 g/mol. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. Find Atomic weight of Manganese (Mn) or Find Atomic weight and density of over 118 known elements like atomic weight or density of Hydrogen, Helium, Carbon, Sodium, Nitrogen, Oxygen, Iron, Silicon, Aluminum, Copper, Silver, Gold, Platinum, Phosphorus, Magnesium and other elements.
