Solution: For many years the extraction of gold-that is, the separation of gold from other materials-involved the use of potassium cyanide:4Au + SKCN + O2 + 2H2O → 4KAu(CN)2 + 4KOHWhat is the minimum amount of KCN in moles needed to extract 32.8 g of gold?

Problem

For many years the extraction of gold-that is, the separation of gold from other materials-involved the use of potassium cyanide:

4Au + SKCN + O2 + 2H2O → 4KAu(CN)2 + 4KOH

What is the minimum amount of KCN in moles needed to extract 32.8 g of gold?
