Calculate the average volume per molecule for an ideal gas at take the cube root to get an estimate of the average distance between molecules. How does this distance room temperature and atmospheric pressure. Then compare to the size of a small molecule like N2 or H20? tely the number of protons in a gram of
Air a. What is the volume of air in the room where you are right now? (You can measure the length, width, and height of the room with a measuring tape, or you can estimate these quantities. Just make sure you convert your answer to SI units.) b. What is the temperature in this room? (in SI units) c. Look up the current barometric pressure in your area, and convert it to SI units. d. Use the information from steps...

Interconverting wavelength, frequency and photon energy It takes 157 kJ/mol to break a nitrogen-oxygen single bond. Calculate the maximum wavelength of light for which a nitrogen-oxygen single bond could be broken by absorbing a single photon. Round your answer to 3 significant digits. x 5 ?
Calculate the mass of nitrogen present in a volume of 3000 cm3 if the temperature of the gas is 22.0 ∘C and the absolute pressure 2.00×10−13 atm is a partial vacuum easily obtained in laboratories. The molar mass of nitrogen (N2) is 28.0 g/mol . Express your answer in kg
A nitrogen molecule has a diameter of about 0.29 nm. The mean free path of a nitrogen molecule in a tank of dry nitrogen at room temperature (293 K) and standard pressure (1 atm) is about 0.10 µm. A tank containing nitrogen at standard temperature (273 K) and pressure has volume V. If the tank is compressed by means of a piston to 20% of its original volume, what is the mean free path for a nitrogen molecule under the...
