How many moles of helium are in a Superman ballon of volume 8.5 L at 92.3 kPa and 287 K?

Answer : The number of moles of helium are, 0.329 mol.

Explanation :

To calculate the moles of helium gas we are using ideal gas equation.

where,

P = Pressure of gas = 92.3 kPa = 0.911 atm

V = Volume of gas = 8.5 L

n = number of moles  = ?

R = Gas constant =

T = Temperature of gas = 287 K

Now put all the given values in above equation, we get:

Thereofore, the number of moles of helium are, 0.329 mol.
