A spherical balloon with a diameter of 8.2 m is filled with helium at 24.6°C and 209 kPa. Determine the mole number and the mass of the helium in the balloon
A spherical balloon with a diameter of 8.2 m is filled with helium at 24.6°C and 209 kPa. Determine the mole number and the mass of the helium in the balloon
In this problem we first calculated volume of sphere by using volume formula. Pressure, temperature and volume converted into , atm, kelvin, and liter respectively.
Then we can get moles by ideal gas law. And by using molar mass we get mass of He in g.
