Answer:
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.
