The importance and effect of fourth postulate of Kinetic molecular theory should be determined on measured pressure of gas. Concept Introduction: The kinetic molecular theory represents the behavior of the gas. With the help of this theory, many scientists had developed laws explaining the properties of the gases like Charles’s law, Boyle’s law etc. There are five postulates are there in this kinetic molecular theory. There is a continuous motion along with straight line travelling in molecules of gas and a direction change observed when they colloids with other molecules and walls of the container. When there is a comparison done in between size of molecules and distance of them, the molecules are small. The collisions between the gas molecules and the container walls results into the pressure applied by a gas. The gases do not have any attraction and repulsion forces thus, the collisions are elastic, or no energy is lost by the gaseous molecules. The temperature of gas in Kelvin unit is directly proportional to the kinetic energy of the gas.

Question

need help not sure what am doing wrong step by step please answer is 971A During the lecture, we calculated the Debye length at physiological salt concentrations and temperature, i.e. at an ionic strength of 150 mM (i.e. 0.150 mol/l) and a temperature of T=310 K. We predicted that electrostatic interactions are effectively screened beyond distances of 8.1 Å in solutions with a physiological salt concentration. What is the Debye length in a sample of distilled water with an ionic strength of 10.0 µM (i.e. 1.00 * 10-5 mol/l)? Assume room temperature, i.e. T= 298 K, and provide your answer as a numerical expression with 3 significant figures in Å (1 Å = 10-10 m).
