WebRelative molecular weight of HgI2: 454.39894 Molar mass of HgI2: 454.39894g/mol (0.4544kg/mol) Calculation of the relative molecular and molar mass of HgI2 Mr[HgI2] = Ar[Hg] + Ar[I] * 2 = 200.59 + 126.90447 * 2 = 454.39894 Molar mass (kg/mol) = Mr[HgI2] … WebReferring to the periodic table, the atomic mass of K is 39.10 amu, and so its molar mass is 39.10 g/mol. The given mass of K (4.7 g) is a bit more than one-tenth the molar mass (39.10 g), so a reasonable “ballpark” estimate of the number of moles would be slightly greater than 0.1 mol. otto trading unimed massager
