Xenon fluoride can be prepared by heating a mixture of xe and f2 gases to a high temperature in a pressure-proof container. Assume that xenon gas was added to a 0. 25 liter container until its pressure reached 0. 12 atm at 0. 0°c. Fluorine gas was then added until the total pressure reached 0. 72 atm at 0. 0°c. After the reaction was complete, the xenon was consumed completely, and the pressure of the f2 remaining in the container was 0. 48 atm at 0. 0°c. What is the empirical formula of the xenon fluoride?
