Water is added to 4.267 grams of UF6. The only products are 3.730 grams of solid containing only oxygen, uranium, and the fluorine and 0.970 gram of a gas. The gas is 95.0% fluorine, and the remainder is hydrogen.
1. Calculate the empirical formula of the gas from these data.
2. What fraction in the gas after the reaction and what fraction of the fluorine of the original compound is in the solid.
