Xenon and fluorine will react to form binary compounds when a mixture of these two gases is heated to 400^oC in a nickel reaction vessel. A 100.0-mL nickel container is filled with xenon and fluorine giving partial pressures of 1.24 atm and 10.10 atm, respectively, at a temperature of 25^oC. The reaction vessel is heated to 400_oC to cause a reaction to occur and then cooled to a temperature at which F₂ is a gas and the xenon fluoride is a nonvolatile solid. The remaining F₂ gas is transferred to another 100.0-mL nickel container where the pressure of F₂ at 25_oC is 7.62 atm. Assuming all of the xenon has reacted, what is the formula of the product?
