Problem 1
A spherical balloon of 21 cm diameter is to be filled with hydrogen at STP from a cylinder containing the gas at 20 atm and 27°C. If the cylinder can hold 2.82 l of water, calculate the number of balloons that can be filled up.
Solution
We must understand first that the gas in the cylinder is at 20 atm and 27°C while it filling the balloons requires STP conditions. If we calculate the volume of the gas at STP, it comes out to be,
![]()
V2 = 51.324 L
This means as we fill the gas at STP, the volume of the gas expands to 51.324 l. It is this expansion that leads to filling of the gas in balloons. But since the cylinder’s volume ...
