The combined gas law states that for a fixed amount of gas, the quantity PVIT is constant. This is often expressed by the equation PV1 PV2 T2 where P is the pressure, V is the volume, and T is the temperature, and the subscripts 1 and 2 denote two different conditions. Rearrange the combined gas law to solve for T2. T2 = A gas with an initial pressure of 1.42 atm, an initial temperature of 223 K, and an initial volume of 14.1 L is heated. The final pressure of the gas is 4.44 atm and the final volume of the gas is 11.2 L. What is the final temperature (T2) of the gas? T, = K
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…
