1.	The empirical formula of a gaseous fluorocarbon is CF2. At a certian temperature and pressure, a 1 L volume hold 8.95 g of this fluorocarbon. Under the same conditions, 1 L volume holds only 1.70 g gaseous F2. Thus, fluorocarbon is_______.(F = 19)
Answer» The empirical formula of a gaseous fluorocarbon is $C F_{2}$ . At a certian temperature and pressure, a 1 L volume hold 8.95 g of this fluorocarbon. Under the same conditions, 1 L volume holds only 1.70 g gaseous $F_{2}$ . Thus, fluorocarbon is_______. (F = 19)
