InterviewSolution

1.	Balloons of 4L capacity are to be filled withHydrogen at a pressure of 1 atm and 27°Cfrom an 8L cylinder containing Hydrogenat 10 atm at the same temperature. Thenumber of balloons that can be filled is
Answer» Consider capacity of each balloon =n1 moles Total moles of gas =n2 molesFrom PV=nRT (R=0.0821LatmK-1mol-1)n1=0.162 molesAnd n2 = 3.25 moles.therefore 20 balloons can be filled
