- Ideal Gas Law Practice Name If you need a refresher on Ideal Gas Law, go back to your Ideal Gas Law Reading Assignment from last week! On all of the following, you'll need to make sure to convert pressures to atm and convert temperatures to Kelvin in order to be able to use the R gas constant on your equation sheet! Given: Ideal Gas Law = then P= pressure V = volume R= ideal gas consent PV=nRT namount of substance n=PV/TR P=nRT/V I = temperature V=nRT/P T=PV/nR R=PV/nT 1. What pressure is required to contain 0.023 moles of nitrogen gas in a 4.2 L container at a temperature of 20.°C? 2. Oxygen gas is collected at a pressure of 123 kPa in a container which has a volume of 10.0 L. What temperature must be maintained on 0.500 moles of this gas in order to maintain this pressure? Express the temperature in degrees Celsius. 3. How many moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100. °C? After determining the number of moles,…arrow_forward1.
