The volume of a goodyear blimp is 2.5x10^7 l, which is occupied by 1.7x10^6 mol of helium. what is the internal pressure of the blimp at 22c

1.7 bar

Explanation:

We can use the Ideal Gas Law to calculate the individual gas pressure.

pV = nRT     Divide both sides by V

 p = (nRT)/V

Data:   n = 1.7 × 10⁶ mol

R = 0.083 14 bar·L·K⁻¹mol⁻¹

T = 22 °C

V = 2.5 × 10⁷ L

Calculations:

(a) Change the temperature to kelvins

T = (22 + 273.15) K

  = 295.15 K

(b) Calculate the pressure

p = (1.7 × 10⁶ × 0.083 14 × 295.15)/(2.5× 10⁷)

  = 1.7 bar
