In the laboratory you dissolve 22.8 g of chromium(III) acetate in a volumetric flask and add water to a total volume of 250 mL. What is the molarity of the solution? M. What is the concentration of the chromium(III) cation? M. What is the concentration of the acetate anion?

The molarity of the chromium(III) acetate solution 0.3982 M.

0.3982 M is the concentration of the chromium(III) cation.

1.1946 M is the concentration of the acetate anion.

Explanation:

Mass of chromium(III) acetate = 22.8 g

Molar mass of chromium(III) acetate = 229 g/mol

Total volume of the solution of chromium(III) acetate =  V = 250 mL = 0.250 L

1 mL = 0.001 L

The molarity of the chromium(III) acetate solution :

The molarity of the chromium(III) acetate solution 0.3982 M.

According to reaction, 1 mole of chromium(III) acetate gives 1 mole of chromium(III) ions and 3 moles of acetate ions.

So

0.3982 M is the concentration of the chromium(III) cation.

1.1946 M is the concentration of the acetate anion.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
