Be sure to answer all parts. Fluorine is so reactive that it forms compounds with materials inert to other treatments. Fluorides of xenon can be formed by direct reaction of the elements at high pressure and temperature. Under conditions that produce only the tetra− and hexafluorides, 1.85 × 10−4 mol of xenon reacted with 5.00 × 10−4 mol of fluorine, and 9.00 × 10−6 mol of xenon was found in excess. What are the mass percents of each xenon fluoride in the product mixture?
