Partial Pressure and the Ideal Gas Law 14 of 20 I Review Constants Periodic Table Air is about 78.0% nitrogen molecules and 21.0% oxygen molecules. Several other gases make up the remaining 1% of air molecules. The ideal gas law, PV = nRT is independent of the kind of gas. In other words, the pressure exerted by a given number of ideal gas particles is the same whether the sample consists of all one type of particle or a mixture of different kinds of particles Therefore, the pressure exerted by a mixture of gases can be expressed as follows: Plotal (nett nyt...) ICT RT nutnat --RT Part A V What is the partial pressure of nitrogen in air at atmospheric pressure (1 atın)? Assume ideal behavior. Express your answer to three significant figures and include the appropriate units. View Available Hint(s) A partial pressure is the pressure exerted by just one type of gas in a mixture. A partial pressure is calculated using only the number of moles of that particular gas, instead of the total number of moles: P1 = nRT Pz = etc. B = RT HA ? The sum of the partial pressures is equal to the total pressure in the mixture Protal =R1+R+B+...
