When elemental sulfur, , is heated with , a gas forms that contains only sulfur and fluorine. The following tests were done to characterize this gaseous product. The density of the gas was found to be 0.807 at 152 and 35 . When the gas reacts with water, all the fluorine is converted to aqueous. A 480- sample of the dry gas at 125 and 28 , when reacted with 80.0 of water, yielded a 0.080 solution of. What is the molecular formula for the gaseous product?
