Question

The effect of chlorofluorocarbons on the depletion of the ozone layer is well known. The use of substitutes, such as CH3CH2F(g), fluoroethane, has largely corrected the problem. Calculate the volume occupied by 0.208 mol of CH3CH2F(g) at a temperature of 298.15 K and a pressure of 1 atm.

4.87 L


8.40 L


6.46 L


5.01 L

Answer 1

• PV=nRT
• V=nRT/P
• V=0.208(R)(298.15)/1
• V=62R
• V=5.146L
