Portable lanterns and stoves used for camping often use a mixture of hydrocarbons
for fuel. One such hydrocarbon is an alkane called n-pentane. These lanterns and stoves
are often difficult to light on a cold day because the fuel has a low vapor pressure at low
temperatures. Determine the vapor pressure of n-pentane on a night when the temperature
is 0.0 °C. The enthalpy of vaporization of n-pentane is 27.6 kJ/mol, and its boiling point
is 36.0 °C.
A) 228 torr
B) 367 torr
C) 184 torr
D) 479 torr
E) 209 torr
