1) Calculate the root mean square speed for nitrogen gas at a temperature of 35.000C. 2)A perfect gas sample contains 6.2 x 1022 molecules per cubic meter at 205 K. Calculate the pressure of this gas and express the answer in units of Pascals, bar, atm, and mmHg. 3)A flask containing oxygen has a volume of 3.5 dm at a pressure of 3.5 bar. Another flask with a volume of 5.0 dm contains neon at a pressure of 5.0 bar....
Molecules in a sample of a gas move at a variety of speeds. Molecular speed can be described by the root-mean-square speed of the gas, which is the square root of the average of the squares of the speeds of all the gas molecules. What is the rms speed of a sample of O2 at 12.49 °C, in m/s? A typed answer is prefered. Answer should be in significant figures.
