Fluorine is so reactive that it forms compounds with mate-rials inert to other treatments.(a) When 0.327 g of platinum is heated in fluorine, 0.519 g of adark red, volatile solid forms. What is its empirical formula?(b) When 0.265 g of this red solid reacts with excess xenon gas,0.378 g of an orange-yellow solid forms. What is the empiricalformula of this compound, the first to contain a noble gas?(c) Fluorides of xenon can be formed by direct reaction of the el-ements at high pressure and temperature. Under conditions thatproduce only the tetra- and hexafluorides, 1.85x10^-4mol ofxenon reacted with 5.00x10^-4mol of fluorine, and 9.00x10^-6mol of xenon was found in excess. What are the mass percents ofeach xenon fluoride in the product mixture?
