Problem

Qualitative analysis indicates that a chemical compound contains only the elements cobalt and chlorine. A quantitative analysis indicates that this compound is 45.3 percent cobalt by mass. In theory, all of the cobalt in a give sample of this compound could be isolated by appropriate chemical transformations. If these chemical transformations are carried out perfectly, what mass of the compound in grams would be required for the isolation of 77.9 grams of cobalt?
