- The temperature at state A is 20.0ºC, that is 293 K. How many moles of ideal gas is there in the container? 1.00 atm = 1.00×105 Pa. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.1.1 m3. The mass of the balloon 3. Consider a hot-air balloon with fixed volume VB envelope, whose volume is to be neglected in comparison to VB, is mL balloon shall be started, where the external air temperature is T = 20°C and the normal 0.187 kg. TheHi, could I get some help with this macro-connection physics problem involving moles and the Ideal Gas Law? The set up is: How many moles are there in a cubic meter of an ideal gas at 100 degree celsius (C) to 4 digits of precision with a pressure of 0.25 atm, assuming 1 atm = 101325 N/m2 with kB = 1.38e-23 J/K and NA = 6.022e23?

- (a) 0.3740 moles of krypton gas is placed in a 9.75 L container at 239 K. Find the pressure of the gas in bar? (b) What is the average kinetic energy per mole of krypton gas atoms featured in the previous part? Report your answer in J/mol.A3] a) Find the temperature of 1 mole of oxygen molecules if they occupy a volume of 4 L and have a pressure of 6 x 10° Pa. You should treat the oxygen as an ideal gas and take the value of the universal gas constant to be R = 8.31J mol1 K-. b) What is the density of the oxygen? You may assume that the mass of I mole of oxygen molecules is 32 g. c) What is the mean square velocity of the oxygen molecules? d) State two assumptions of the kinetic theory of ideal gases that the van der Waals model does not require to be true.Suppose you have 0.53 moles of an ideal gas. What is the average kinetic energy of that gas (in units of kJ) if the temperature of the gas is 280.2K? Note: It is understood that the unit of your answer is some number of kilo-Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("kJ" in this case), you answer will be counted wrong.
