Answer to Question #133947 in General Chemistry for Yelgab Xela

Question

The metathesis reaction between chromium (III) acetate and potassium carbonate is shown below

2 Cr(C2H3O2)3 (aq) + 3 K2CO3 (aq) ➝ 6 KC2H3O2 (aq) + Cr2(CO3)3 (s)

How many grams of solid chromium (III) carbonate can be produced by the reaction of 250.0 ml of 0.650 M chromium (III) acetate solution with 200.0 ml of 0.500 M potassium carbonate solution?

The formula weight of Cr2(CO3)3 = 284.016 g/mol.

Answer
grams of Cr2(CO3)3.
