When elemental sulfur,S8,is heated with AgF,a gas forms that contains only sulfur and fluorine. The following tests were done to

Question

characterize this gaseous product.
*The density of the gas was found to be 0.807g/L at 152mmHg and 35 degrees celsius.
*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 degrees celsius, when reacted with 80.0 mL of water, yielded a 0.080 M solution of HF. What is the empirical formula?

Answer 1

The empirical formula is SF4.
