Let n balloons be filled; thus, total volume of hydrogen used in filling balloons
=4.851×n litre
Total volume of hydrogen in the cylinder at NTP,
V=
300×1
20×2.82×273
=51.324 litre
Actual volume of H

to be transferred to balloons
=51.324−2.82(2.82 litre retained in the cylinder)
=48.504 litre

Solution :
Volume of gas at NTP is ,
P1V1=P2V2
6×6=1×V2
V2=36 litres.
Outcoming gas = 36-6 =30 litres
No of balloon =30/5=6
