PLEASE SHOW ALL WORK!! Thank you so much!

What is the mean free path of molecules in an ideal gas in which the mean collision time is 2.00 x 10'10 s, the temperature is 313K, and the mass of the molecules is 6.00 x 10'25 kg? Assume that the molecules are moving at their root-mean-square speeds. The Boltzmann constant is 1.38 x 10'23 J/K. Give your answer in Angstroms ( 1 Angstrom = 10'10 m} A sealed 24.0-m3 tank is lled with 1.423 moles of oxygen gas (02) at an initial temperature of 270 K. The gas is heated to a nal temperature of 499 K. The ATOMIC mass of oxygen is 16.0 g/mol, and the ideal gas constant is R = 8.314 J/mol - K = 8.314 J/mol - K. The nal pressure of the gas in kiloPascals is closest to
