WebCommunity Answer [Cr (H2O)6]3+ is violet whereas [Cr (NH3)6]3+ is yellow. The wavelength ... To find the number of moles of CoCl3 in the solution, we need to divide the given mass by the molar mass of CoCl3. Molar mass of CoCl3 = 58.933 g/mol + 35.453 g/mol x 3 = 165.87 g/mol Number of moles of CoCl3 = 2.675 g / 165.87 g/mol = 0.0161 mol WebThe variety of color among transition metal complexes has long fascinated the chemists. For example, aqueous solutions of [Fe(H2O)6]3+ are red, [Co(H2O)6]2+ are pink, [Ni(H2O)6]2+ are green, [Cu(H2O)6]2+ are blue and [Zn(H2O)6]2+ are colorless.
