At high pressures, real gases do not behave ideally. Calculate
the pressure exerted by 27.0 g H2 at 20.0°C in a 1.00 L container
assuming in Part 1 non-ideal behavior and in Part 2 ideal
behavior.
At high pressures, real gases do not behave ideally. Calculate
the pressure exerted by 33.0 g H2 at 20.0°C in a 1.00 L
container assuming in Part 1 non-ideal behavior and in Part 2 ideal
behavior.
Part 1)Use the van der Waals equation and data in the hint to
calculate the pressure exerted= ____atm
Part 2)Now, calculate the pressue excerted assuming that the gas
behaves as an ideal gas.= _____ atm
At high pressures, real gases do not behave ideally. (a) Use the
van der Waals equation and data in the text to calculate the
pressure exerted by 29.0 g H2 at 20 degree C in a 1.00 L container.
(b) Repeat the calculation assuming that the gas behaves like an
Ideal gas.
The gases behave as ideal at low pressure, however, at high
pressure they deviate from the ideal behavior. Compare the input
power required(in kW)for compressing oxygen gas by first assuming
ideal behavior then the real behavior. Take inlet state at 10 MPa,
14°C and the final state after compression is 15 MPa, 127°C. You
can ignore the effect of gravity and motion of the system.Assume
mass flow rate of the gas as 9 kg/min
Calculate the vapor pressure of water above a solution prepared
by dissolving 27.0 g of glycerin (C3H8O3) in 135 g of water at 343
K. (The vapor pressure of water at 343 K is 233.7 torr.)
Ph2o=?
Calculate the mass of ethylene glycol (C2H6O2) that must be
added to 1.00 kg of ethanol (C2H5OH) to reduce its vapor pressure
by 9.00 torr at 35∘C. The vapor pressure of pure ethanol at
35∘C is 1.00×102 torr.
m=?
Calculate the vapor pressure of a solution containing 27.0 g of
glycerin (C3H8O3) in 119 mL of water at 30.0 ∘C. The vapor pressure
of pure water at this temperature is 31.8 torr. Assume that
glycerin is not volatile and dissolves molecularly (i.e., it is not
ionic) and use a density of 1.00 g/mL for the water.
23 mg of nitrogen gas, assumed to behave ideally, at a pressure
of 88 torr and at 22oC undergoes an adiabatic free
expansion into a vacuum (Joule experiment) to a final pressure of
34 torr.
a) Is the process reversible? Why or why not?
b) What is the final temperature of the system? Why? [ answer
should be 22oC]
c) What is ∆S for the system?
Calculate the pressure in cm H2O
exerted in the closed end of an apparatus if the atmospheric
pressure is 720.0 torr and the height of the water coloumn is
22.3cm.

how do I calculate area of pinhole and pinhole diameter?
ln(P/P0) = -Ct
dP/P = - (A/V)(RT/2πM)1/2 dt = -C dt
(volume= 285cm3, T= 298.15K)
I got relaxation constant 0.01049 microns/second =
C
This is for N2 ( nitrogen)
How do i solve A (pinhole are)?
For ethane, Pc = 48.2 atm and Tc = 305.4 K. Calculate
the pressure exerted by 50.0 g of C2H6 in a
200-cm3 vessel at 37.5°C.
(c) the Redlich–Kwong equation; (d) the virial equation, given
that for ethane B = -179 cm3/mol and C = 10400
cm6/mol2 at 30°C, and B = -157

50°C.
(c) P = ? atm
(d) P = ? atm
