Definitions of molecular mass, molecular weight, molar mass and molar weight An element’s mass number (A) is the sum of the number of protons and the number of neutrons. The small contribution of mass from electrons is disregarded in calculating the mass number. This approximation of mass can be used to easily calculate how many neutrons an element has by simply subtracting the number of protons from the mass number. The molar mass of Fe³⁺ is 55.845 g/mol. The only difference between an Fe atom and an Fe³⁺ ion is three electrons. The electrons have so little mass compared to the rest of the atom that their masses can be ignored.
Aug 2, 2012 How many protons, neutrons, and electrons are present in each of the nuclides below? Iron (Fe): atomic number = 26, mass number = 56; Iodine-
its atomic number is 26 so thats how many protons there are. Then you take 56-36=30.

Molar mass is the mass of one mole of an element or compound. "1 mol Fe"="55.845 g Fe" lArr from periodic table Another way to indicate molar mass is as follows: "molar mass Fe"=55.845 "g/mol Molar mass calculations are explained and there is a JavaScript calculator to aid calculations.
