The Ideal Gas Law

Q. The effect of chlorofluorocarbons (such as CCl2F2(g)) on the depletion of the ozone layer is well known. The use of substitutes, such as CH3CH2F(g), for the chlorofluorocarbons, has largely corrected the problem. Calculate the volume (in L) occupied by 14.0 g of each of these compounds at STP. (a) CCI2F2(g) L (b) CH3CH2F(g) L
