Question: in a 50 ml erlenmeyer flask were combined at 25...

Question details
  1. In a 50 mL Erlenmeyer flask were combined at 25 C 10 mL of water, 1.482 g of chromium (III) chloride hexahydrate, 1.75 mL of 2,4-pentanedione (C5H8O2), and 1.214 g of sodium acetate. After stirring for 30 minutes, 1.204 g of solid tris(2,4-pentanedionato)chromium (III) (Cr(C5H7O2)3) was isolated. The density of 2,4-pentanedione at 25 C is 0.975 g/mL. The equation for the reaction is shown below.

Cr3+(aq) + C5H8O2 (aq) + C2H3O2(aq) Cr(C5H7O2)3(s) + HC2H3O2(aq)

  1. How much of each product can theoretically be produced?
  2. What was the percent yield of the product?
  3. How much of the non-limiting reactants are left after the reaction?
