Problem 71

To extract gold from its ore, the ore is treated with sodium cyanide solution in the presence of oxygen and water. 4Au(s) + 8NaCN(aq) + O 2 (g) + 2 H 2 O(l) 4NaAu(CN ) 2 (aq) + 4NaOH(aq) a. Determine the mass of gold that can be extracted if 25.0 g of sodium cyanide is used. b. If the mass of the ore from which the gold was extracted is 150.0 g, what percentage of the ore is gold?
