2. What pressure would be exerted by 0.76 mol of O2 gas at 423 K in a 5.4 L container? 3. What volume would 4.2 mol of O2 gas occupy at a temperature of -19°C if the volume at 124°C is 2.7 L?
Question 3 A rigid tank, of 0.5 m volume, contains an ideal-gas mixture at 300 K. The mixture is made up of 2.4 kg of gas A and 1.4 kg of gas B, the molecular weights of which are MA = 32.0 kg/kmole and M 28.0 kg/kmole, respectively. i. Determine the mass fraction of A and B. (3 marks] ii. Determine the mole fraction of A and B. [5 marks] iii. Determine the molecular weight of the mixture. [2 marks]...

A closed tank having a volume of 62 L is filled with 0.1 kg of a gas. A pressure gauge attached to the tank reads 270 kPa when the gas temperature is 20°C. Assuming ideal gas behaviour, the gas in the tank is most likely: cross out Select one: O a. Air; O b. Carbon dioxide; c. Oxygen; cross out cross out d. None of the above cross out An open (to...
Hello,
could you help me with it .
