Zinc Hydrogen Carbonate Zn(HCO3)2 Molar Mass, Molecular Weight Zinc Bromate Zn(BrO3)2 Molar Mass, Molecular Weight. Molar mass of zinc is 65.3800 g/mol Compound name is zinc Convert between Zn weight and moles The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Use uppercase for the first character in the element and lowercase for the second character. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). Since zinc is a chemical element, we can give its atomic weight (the standard atomic weight is 65.38 for zinc) while we can give the molar mass or molar weight for zinc oxide (molar mass is 81.38 g/mol.) because it is a chemical compound. Atomic Mass of Zinc. Zinc Periodate Zn(IO4)2 Molar Mass, Molecular Weight. Basically, you should know how to find the molar masses of any chemical compound now. Molar mass of ZnCl2 = 136.286 g/mol. Atomic mass of Zinc is 65.409 u. Molar mass of ZnO is 81.3794 g/mol Compound name is zinc oxide Convert between ZnO weight and moles For all other compounds, the general idea is the same. Examples: Fe, Au, Co, Br, C, O, N, F. You can use parenthesis or brackets []. Molar mass of ZnSO4 is 161.4426 g/mol Compound name is zinc sulfate Convert between ZnSO4 weight and moles The molar mass of zinc nitrate will be equal to (1 atom x 65 grams/mole of zinc) + (two atoms x 14 grams/mole of nitrogen) + (six atoms x 16 grams/mole of oxygen) = 189 grams/mole of zinc nitrate. Molar Mass: 321.1844 Molecular weight calculation: 65.38 + 35.453*2 ›› Percent composition by element ›› Zinc Chloride molecular weight. Molar Mass: 447.1841 :: Chemistry Applications:: Finding Molar Mass. Definitions of molecular mass, molecular weight, molar mass and molar weight. Convert grams Zinc Chloride to moles or moles Zinc Chloride to grams. It will calculate the total mass along with the elemental composition and mass of each element in the compound.
