The desired substance is iron(II) chloride, Fecl2. The formula mass of FeClz is the following. Fea2·(1)(average atomic mass of Fe) + (2)(average atomic mass of a) - (1X55.85 amu) + (2)(35.45 amu) amu Formula mass in amu is equal to molar mass in g/mol, so the molar mass of FeCl2 is g/mol. Given the equation relating the molar mass of a substance to its formule mass. calculate tho molar mass of a substance Calculate the moleclar masso oemula mass of a substance Supporting Materials Supplemental Data constants and Factors Periodic Table Additional Materials Section 43 a Show My Work (otonn -1.53 points This question has several parts that must be completed sequentialy, If you skip a part of the question, you wil not receive any poin

Solution

FeCl2   = 1* average atomi mass of Fe+ 2* average atomic mass of Cl

              = 1*55.85 amu+ 2*35.45 amu

              = 126.75amu

formula mass of amu is equal to molar mass in g/mole . so the molar mass of FeCl2 is 126.75g/mole
