Answer: Moles are found in a 350.mL solution of 13.5M are 4.725 mol.
Explanation:
Given: Volume = 350 mL (1 mL = 0.001 L) = 0.350 L
Molarity = 13.5 M
Molarity is the number of moles of a substance present in a liter of solution.
Therefore, moles of present in the given solution are calculated as follows.
Thus, we can conclude that moles found in a 350.mL solution of 13.5M are 4.725 mol.
The geometry of a complex is determined by the number of ligands that surround the central atom/ion. There are four ligands in the complex. The coordination number of the complex is 4. The oxidation number of Rh is zero. The preferred geometrical shape of this complex is square planar.
Complexes are formed when Lewis bases called ligands become attached to a central metal atom or ion. The coordination number of the complex refers to the number of ligands that surround the central metal atom/ion.
In this case, four ligands surround the central Rhodium atom in a zero oxidation state.
Since we were told that the compound exhibits cis/trans isomerism then it can not have a tetrahedral geometry. It must have a square planar geometry as tetrahedral complexes do not exhibit cis/trans isomerism.
The image of the cis- and trans- geometrical isomers of the compound is attached to this answer.
