Theoretical Yields – Level 3 You are synthesizing KTOF3 using similar conditions to what we encountered in the lab.6.5 g potassium oxalate monohydrate0.85 M, 125 mL Ferric Chloride (FeCl3 aq.) You obtained 4.92 g of KTOF3. Given:potassium oxalate monohydrate mw: 184.23 g/molKTOF3 mw: 491.24 g/mol Calculate the percent yield.

Chelation – Practical Applications in Food – Level 2 EDTA (Ethylenediaminetetraacetic acid) when fully deprotonated can act as a hexadentate molecule.  This molecule is found in a variety of foods to mask the flavor of metals. When reacted with iron, it becomes ferric EDTA. How many molecules of EDTA would be required to react with a single iron atom?  Hint: Look at and consider the number of binding sites of EDTA via Lab Manual Pg 160 Fig 2.Note: Ignore the floating H2O molecules in the top right.Clarification: The molecule presented above is in its di-protonated form. Please reread the question and consider what we discussed in the lab.

1.  Mining Inc. recently reported $15,000 of sales, $7,000 of operating costs other than depreciation, and $1,200 of depreciation. The company had no amortization charges, it had outstanding $7,500 of bonds that carry a 6.25% interest rate, and its federal-plus-state income tax rate was 25%. How much was the firm’s net income after taxes? Meric uses the same depreciation expense for tax and stockholder reporting purposes.
