Question

A spherical balloon of 21 cm diameter is to be filled up with hydrogen at NTP from a cylinder containing the gas at 20 atm and 27°C. The cylinder can hold 2.82 litre of water at NTP. Calculate the number of balloons that can be filled up.​

Answer 1

Answer:

=> 10 ballons

Explanation:

radius (r) = diameter (d)/2 = 21/2 cm

=> Volume of one balloon = 4/3(πr^3)

= 4/3(3.14)(21/2)

= 4847 cm^3

= 4.847 L

=> Volume of hydrogen in the cylinder

= 20*2.82*273/300

= 51.324 L

=> Volume of hydrogen to be filled in cylinder = 51.324 - 2.82

= 48.504 L

=> Number of balloons filled = 48.504/4.847

= 10
