Liquid air is available (79 mol% of nitrogen and 21 mol% of oxygen) and it is required to obtain a fraction whose oxygen content is 90% (mol), for which part of the mixture evaporates to the atmospheric pressure. Determine the fraction of evaporated mixture, taking as the average value of relative volatility 4.12

When air (21 mol% O2, 79 mol% N2) is placed in contact with 1000
cm3 of liquid water at body temperature, 37°C, and 1 atm absolute,
approximately 14.1 standard cubic centimeters [cm3(STP)] of gas are
absorbed in the water at equilibrium. Subsequent analysis of the
liquid reveals that 33.4 mol% of the dissolved gas is oxygen and
the balance is oxygen
a) Estimate the Henry’s law coefficients (atm/mole fraction) of
oxygen and nitrogen at 37°C
b) An adult absorbs approximately...

A plant distills liquid air to produce oxygen, nitrogen, and
argon. The percentage of impurity in the oxygen is thought to be
linearly related to the amount of impurities in the air as measured
by the “pollution count” in parts per million (ppm). A sample of
plant operating data is shown below:

linearly related to the amount of impurities in the air as measured
by the pollution count. in parts per million (ppm). A sample of
plant operating data is show below. (a) state the hypothesis of a
linear relationship between oxygen purity and input air purity and

Assume for the moment that air consists of 80.00% nitrogen (N2)
and 20.00% oxygen (O2) by volume. Use these figures and typical
values for temperature and pressure (1.000atm and 25.00°C) to
calculate the density of air in g/L.

A tank containing air at atmospheric pressure must be purged
with pure nitrogen until the oxygen concentration is 5 ppm. The
tank can withstand a vacuum, so vacuum purging is considered. The
vacuum line used produces an absolute pressure of 6 mmHg. How many
vacuum cycles are necessary?

A 1500 liter chamber has 80% nitrogen + 20% Oxygen. If you
replace the air with 100% Oxygen at 240, 300, 400 LPM when do you
reach 95% and 99% Oxygen?
What volume of air at STP is needed for complete combustion of 1 mol of CS2? (air is 20% oxygen).
a. Find density of nitrogen at 17ºC and 700 torr.
b. What volume of air at STP is needed for complete combustion of 1 mol of CS2? (air is 20% oxygen).
