Question

Use the Ideal Gas Law to calculate the number of moles (n) of helium in a 4000 Liter weather balloon near the top of Mt. Rainier with a pressure of 0.6 atm and temperature of 260K.

Answer 1

Answer: 112.5moles

Step-by-step explanation:

P= 0.6atm, V= 4000L, R= 0.082, T= 260K

Applying PV = nRT

0.6×4000= n×0.082×260

Simplify n= (0.6× 4000)/(0.082×260)

n= 112.5moles
