WebFirst, you can calculate the molar mass of FeCl2 by adding the molar masses of Fe (55.845 g/mol) and 2 atoms of Cl (2 times (35.446 g/mol). This gives a molar mass of 126.737 g/mol. Since each mole is 126.737 grams, you multiply 3.5 mols by 126.737 grams, giving you 443.58 grams. WebThe outer diameters of the two parts are d_1=1.6 d1 = 1.6 in. for the brass core and d_2=2.0 in d2 = 2.0in. for the steel sleeve. The shear moduli of elasticity are G_b=5400 Gb = 5400 ksi for the brass and G_s=12,000 Gs = 12,000 ksi for the steel.
