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. Air is about 78.0% nitrogen molecules and 21.0% oxygen molecules. Several other gases make up the remaining 1% of air molecules. Therefore, the pressure exerted by a mixture of gases can be expressed as follows: Part A Tota RT Ptotal = V What is the partial pressure of nitrogen in air at atmospheric pressure (101 kPa)? Assume ideal behaviour. 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: Express your answer to three significant figures and include the appropriate units. • View Available Hint(s) RT P = V P = nRT P= nRT etc. The sum of the partial pressures is equal to the total…
