Derive a linear relationship between gas density and tem-perature, and use it to estimate the value of absolute zero temperature (in oC to the nearest 0.1oC) from an air sample whose density is 1.2930 g/ L at 0.0oC and 0.9460 g/ L at 100.0oC. Assume air obeys the ideal gas law and that the pressure is held constant.
Answer to relevant QuestionsA chemist weighed out 5.14 g of a mixture containing unknown amounts of BaO(s) and CaO(s) and placed the sample in a 1.50-L flask containing CO2(g) at 30.0oC and 750. torr. After the reaction to form BaCO3(s) and CaCO3(s) ...Derive Dalton’s law of partial pressures from the ki-netic molecular theory of gases. What assumptions are necessary? Calculate the number of stages needed to change a mixture of 13CO2 and 12CO2 that is originally 0.10% (by moles) 13CO2 to a mixture that is 0.010% 13CO2 by a gaseous diffusion process. (The mass of 13C is 13.003355 amu.) An ideal gas at 7oC is in a spherical flexible container having a radius of 1.00 cm. The gas is heated at constant pressure to 88oC. Determine the radius of the spherical container after the gas is heated. (Volume of a ...A sample of nitrogen gas was collected over water at 20.oC and a total pressure of 1.00 atm. A total volume of 2.50 × 102 mL was collected. What mass of nitrogen was collected? (At 20.oC the vapor pressure of water is 17.5 ...
