If you increase pressure on one liter of nitrogen the volume occupied by that liter of gas will decrease.
One liter of nitrogen can be bought for six cents if by the truckload, or a dollar or two in exceptionally small quantities. It's actually cheaper to produce than bottled water.
you need to state the temperature and pressure. The ideal gas law shows that pressure is inversely proportional to volume and temp is proportionally to volume, so volume, and thus, concentration of molecules, thus weight would be different depending on the temperature and pressure.
Around 0.12 percent, it differs in different countries depending on the environment and altitude.
You would need to defineTemp and pressure to determine the volume of a liter. Then density = kgm/vol
one liter (or litre) is 1000 ml. 2 liters is 2000, so subtract 1650 from 2000. The result is your answer.
Two liters divided by 3.2 ATM => 0.625 liters / 1 ATM >> ought to do it.
It all depends on a litre of what.
The density of nitrogen is 1.251 g/liter at 0° C (32° F) and 1 atmosphere pressure. The density of ultrapure nitrogen gas at 0 0C and 101,325 kPa is: 1,251 g/L and at 15 0C is 1,185 g/L. 0.0012506 g/cm3
About twice the size of a 2 liter soda bottle. Liquid nitrogen is extremely cold- the container must be vacuum insulated, or the liquid nitrogen quickly turn to gas.
2 volumes of ammonia gas.
To work this out there are two possible methods, the first uses knowledge about densities: At it boiling point, Liquid Nitrogen has a density of 807.0 grams per liter At Standard Temperature and Pressure, Nitrogen Gas has a density of 1.251 grams per liter Thus:- 25 liters of Liquid Nitrogen will weigh 25*807 = 20175 grams At STP 20175 grams of Nitrogen Gas will occupy 20175/1.251 = 16127.1 liters. The second method is to use the published expansion ratio for Liquid Nitrogen: Liquid Nitrogen has a liquid-to-gas expansion ratio of 1:694 at 20°C (68 °F) Thus:- 25*694=17350 liters. You will see the numbers are similar but slightly different, of the two I would be more confident in the density calculation method result. Although I suspect most people would use the expansion ratio method.
20.95%oxygen and 78.08% nitrogen
1 Kilometer per liter = 2.35 miles per US gallon So, 10 kl per liter = 23.5 mpg A close estimate (if you're converting in your head) is to double the kilometers per liter value, and increase the result by 15%.
One liter of nitrogen can be bought for six cents if by the truckload, or a dollar or two in exceptionally small quantities. It's actually cheaper to produce than bottled water.
assume that the air is originally at atmospheric pressure
1 L nitrogen gas at 0 oC and 1 atm has the mass 1,251 g.
you need to state the temperature and pressure. The ideal gas law shows that pressure is inversely proportional to volume and temp is proportionally to volume, so volume, and thus, concentration of molecules, thus weight would be different depending on the temperature and pressure.
