The volume that "escapes" is V 2 minus 2.05 L. Usually, a Charles' Law problem asks for what the volume is at the end (the V 2 in this question) or at the start, before some temperature change. This question asks you for the difference between V 1 and V 2.
A sample of gas has an initial volume of 25 L and an initial pressure of 3.5 atm. If the pressure changes to 1.3 atm, find the new volume, assuming that the temperature remains constant.
What volume will the gas occupy at STP? At a certain temperature, molecules of methane gas, CH4 have an average velocity of 0.098 m/s. What is the average velocity of carbon dioxide molecules at this same temperature? Find the relative rate of diffusion for the gases chlorine, Cl2 and ethane, C2H6.
28 Μαΐ 2020 · What is the molar mass of a gas if 0.281 g of the gas occupies a volume of 125 mL at a temperature 126 °C and a pressure of 777 torr? Answer . 72.0 g/mol. Click here to see a video of the solution
Use your knowledge of the ideal and combined gas laws to solve the following problems. If it involves moles or grams, it must be PV = nRT. 1) If four moles of a gas at a pressure of 5.4 atmospheres have a volume of 120 liters, what is the temperature? 1973 K.
2) What is the volume of 1.00 mole of a gas at standard temperature and pressure? 3) A 113L sample of helium at 27°C is cooled at constant pressure to -78.0°C. Calculate the new volume of the helium. 4) What volume of He is occupied by 2.35 mol of He at 25°C and a pressure of 0.980 atm?
