A20 liter cylinder of helium at a pressure of 150 atm and a temperature of 27°c is used to fill a balloon at 1.00 atm and 37°c. what is the volume of the balloon? a. 0.14 liters b. 3000 liters c. 2900 liters d. 2400 liters e. 3100 liters
The number of moles will remain the same in the two cases
so we can equate using ideal gas equation which is PV =nRT
V2 = 3100 L
E. 3100 liters
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
= initial pressure of gas = 150 atm
= final pressure of gas = 1 atm
= initial volume of gas = 20 L
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get the final pressure of gas.
Therefore, the volume of the baloon is 3100 L.
the answer is true.this statement is true.
