Nuclear engineers use chlorine trifluoride in the processing of uranium fuel for power plants. This extremely reactive substance is formed as a gas in special metal containers by the reaction of elemental chlorine and fluorine. This is the reaction:
______Cl2(g) + ____ F2(g) + _____ ClF3(g)
When this reaction is run with 53.3 g of Cl2 and 114.0 grams of F2, what mass of chlorine trifluoride will be prepared?
