Calculate the vapor pressure at 20°C of a solution containing 0.61g of naphthalene in 16g of chloroform (CHCl3). Naphthalene (C10H8) has a low vapor pressure and may be assumed to be nonvolatile. The vapor pressure of chloroform at 20°C is 156 torr.
a) The vapor pressure would not change as naphthalene is considered non-volatile.
b) 28.10 torr
c) 20.90 torr
d) 150.65 torr
Answer: d) 150.65 torr
