Question

Calculate the number of moles of helium in a balloon that is inflated to a total pressure of 120 kPawith a volume of 1.3 L at 22°C (NOTE: 1 atm = 101,325 Pa) 0.045 moles 0.064 moles 0.853 moles 15.62 moles

Answer 1

Given v= 1031, T =(22+273) K = 295k P120 R=0.08206 Latamat't- - 120x103 101325 n = PV = 1-188430792x103 = > 1843 02 0.082068 295 = 0.06359961 med 2020-3-25 00:23 I 0.064 moles The correct statement is If the pressure is halved, the volume also doubles.
