What is the molar mass of Fe2Br3? 1.35 x 102 g/mole 3.27 x 102 g/mole 3.51 x 102 g/mole 8.14 x 102 g/mole

OpenStudy (kaylaprincess):

molar mass = grams / number of moles = g/mole to find moles = g / molar mass to find mass = g = molar mass / moles /////////////////////////////////////// Fe2Br3 mass = 2moles x mass Fe + 3 moles x mass Br
