Question
In the preparation of trans-K[Cr(C2O4)2(H2O)2]*2H2O. 7.15 g of oxalic acid dihydrate (MW=126.07) reacted with 1.81 g of potassium dichromate(MW=294.18 g/mol) and 2.52 g of product
In the preparation of trans-K[Cr(C2O4)2(H2O)2]*2H2O. 7.15 g of oxalic acid dihydrate (MW=126.07) reacted with 1.81 g of potassium dichromate(MW=294.18 g/mol) and 2.52 g of product coordination compound(MW=339.19 g/mol) was isolated.
Unbalanced chemical reaction: K2CR2O7 + H2C2O4*2H2O--> K[CR(C2O4)2(H2O2] *2H2O + CO2 + H2O
What is the percent yield of the synthesis?
7.15/126.07= .05671
1.81/294.18=0.006153
2.52/339.19=0.007429
