A helium tank holds a volume of. 02 m^3 at a pressure of 15.5*10^6 Pa and a temperature of 293 K. How many spherical balloons with a radius of. 11 m can be filled with this much helium if the temperature remains constant?

Answer unit is Balloons

We shall find the volume of stored gas at atmospheric pressure.

P₁ V₁ = P₂ V₂

15.5 x 10⁶ x. 02 = 10⁵ x V₂ (atmospheric pressure is 10⁵ Pa)

V₂ = 3.1 m³

volume of one balloon = 4/3 x π r³, r is radius of balloon

= 4/3 π x. 11³

=.050658 m³

no of balloon = total volume to be filled / volume of one balloon

= 3.1 /.050658

= 61.2

= 61
