If 4.87 g of green NiCl2.6H2O is dissolved in 2 mL of water. 5.05 g of white Na2C2O4(s) is dissolved in 50 mL of water. The two solutions are mixed together and stirred for 1 hour and the resulting NiC2O4.2H2O is filtered. Then the NiC2O4.2H2O is heated in an oven to result in 0.84 g of Ni(s). Calculate the percent yield of Ni.
