Answer #1

The vapor pressure of pure component A is 42.0 kPa at 298 K. The
vapor pressure of pure component B is 29.0 kPa at the same
temperature. Which of the two substances has the lower normal
boiling point. Assuming an ideal liquid solution of A and B has
mole fraction A equal to 0.400, What are the partial pressures and
the total pressure over the liquid assuming Raoult’s law applies.

The vapor pressure of water is 3.1672 kPa at 25oC. If
the vapor pressure over a non-electrolyte solution of the
nonvolatile solute urea is 3.1232 kPa when the mass fraction of
urea is 0.0450, what is the experimental value of the molar mass of
urea?

The vapor pressure of diethyl ether (ether) is 463.57 mm Hg at
25°C. How many grams of testosterone, C19H28O2, a nonvolatile,
nonelectrolyte (MW = 288.4 g/mol), must be added to 198.3 grams of
diethyl ether to reduce the vapor pressure to 457.31 mm Hg ?
diethyl ether = CH3CH2OCH2CH3 = 74.12 g/mol. g testosterone

Raoult’s Law Calculations
The vapor pressure of diethyl ether (ether) is
463.57 mm Hg at 25°C.
How many grams of aspirin,
C9H8O4, a
nonvolatile, nonelectrolyte (MW = 180.1 g/mol),
must be added to 224.2 grams of diethyl
ether to reduce the vapor pressure to
458.89 mm Hg ?
diethyl ether =
CH3CH2OCH2CH3
= 74.12 g/mol.

A 1-m3 tank contains 1.042 kg of water vapor at pressure 200
kPa. Determine the temperature in degrees celsius (˚C) using the
van der Waals equation.

At 50.14 K a substance has a vapor pressure of 258.9 torr.
Calculate its heat of vaporization in kJ/mol it if has a vapor
pressure of 161.2 torr at 277.5 K.

Calculate the boiling temperature and the vapor phase mole
fraction y1 at 85 kPa of the binary mixture with the liquid phase
mole fraction x1 = 0.40. Consider the mixture ideal. The saturation
vapor pressures of the components in the mixture are given below
and are T (° C);
P1sat
= exp [14.3 - 2945 / (T + 224)]
P2sat
= exp [14.2 - 2943 / (T + 209)]

pressure of etane at −
58.5 ◦C

The saturation pressure for an unknown substance has been fitted
to temperature using the
following Antoine’s equation:
lnPsat = 8.6866 − (2626.42/(T −146.6))
where [Psat] = [bar] and [T] = [K]. Estimate
the heat of vaporization of this substance at the
normal boiling point.
