Molarity and concentration

In the laboratory you dissolve 20.3 g of iron (III) fluoride in a volumetric flask and add water to a total volume of 125 mL

What is the molarity of the solution? _______ M.

What is the concentration of the iron(III) cation? _______ M.

What is the concentration of the fluoride anion? _______ M.

For the following reaction. You may want to reference while completing this problem. If a reaction mixture initially contains a CO concentration of 0.1490 and a Cl_2 concentration of 0.176 al 1000K. What the equilibrium concentration of CO at 1000 K? Express your answer in molarity to three significant figures. What is the equilibrium concentration of CI_2 at 1000 K? Express your answer in molarity to three significant figures. What is the equilibrium concentration of COCI_2 at 1000 K? Express your answer in molarity to three significant figures.
