When elemental sulfur S8, , is heated with AgF , 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 g/L at 152 mmHg and 35 C .
When the gas reacts with water, all the fluorine is converted to aqueous HF . A 480- mL sample of the dry gas at 125 mmHg and 28 C , when reacted with 80.0 mL of water, yielded a 0.080 M solution of HF .
What is the empirical formula for the gas formed? I solved this "SF" I need the next one
What is the molecular formula for the gaseous product?
