A molecular compund is composed of 60.4% Xe, 22.1% O, and 17.5% f, by mass. When 1.652 grams of the compound was vaporized at 373K and a pressure of 1 atm. It was found to have a volume of 233 ml. Find the molar mass of the compound and determine its molecular formula. What is the Lewis formula of the compund? predict the electonic and molecular geometry using the VSEPR model.
