a)Air is mostly nitrogen, with a molecular mass of 28 g/mol. Sarin has molecular mass of 140.11 g/mol. Using Graham’s Law of effusion, determine the rate of nitrogen effusion into the room compared to the rate of sarin gas effusion. b) Nitrogen gas effuses at the rate of 79.0 mL/s. assuming the same temperature and pressure, at what rate will sarin effuse in mL/s? c)Assuming that nitrogen will behave as an idela gas, calculate the volume, in ml N2 that 1.00 mmol N2 will occupy at STP.
Ideal and Real Gases
Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,
Gas Laws
Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries were made by Charles, Gay-Lussac, Avogadro, and others. Eventually, these observations were combined to produce the ideal gas law.
Gaseous State
It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed forms of matter studied are solids, gases and liquids. The best example of a substance that is present in different states is water. It is solid ice, gaseous vapor or steam and liquid water depending on the temperature and pressure conditions. This is due to the difference in the intermolecular forces and distances. The occurrence of three different phases is due to the difference in the two major forces, the force which tends to tightly hold molecules i.e., forces of attraction and the disruptive forces obtained from the thermal energy of molecules.
An evil mastermind is attempting to take over the world, but he needs your patent for a new power source. He has trapped you in a room and a lethal nerve gas, sarin, is effusing into the room. You must figure out a way to escape in time.
a)Air is mostly nitrogen, with a molecular mass of 28 g/mol. Sarin has molecular mass of 140.11 g/mol. Using Graham’s Law of effusion, determine the rate of nitrogen effusion into the room compared to the rate of sarin gas effusion.
b) Nitrogen gas effuses at the rate of 79.0 mL/s. assuming the same temperature and pressure, at what rate will sarin effuse in mL/s?
c)Assuming that nitrogen will behave as an idela gas, calculate the volume, in ml N2 that 1.00 mmol N2 will occupy at STP.
d) At STP, how many minutes will it take for 1.00 mmol of N2 to effuse?
e) Assuming that sarin will behave as an ideal gas at STP, how many minutes do you have to escape the room before 1..6 mmol of sarin has effused into the room?
