Concept explainers
Interpretation:
The tank will have to contain helium at the pressure of 750mmHg after the balloons are filled then the number of balloons inflated with the gas in the tank is to be determined.
Concept introduction:
The ideal gases are those gases which obey the ideal gas equation and the ideal gas equation is written as
Where, P = pressure of the gas
V = Volume of the gas
R = Gas constant
T = temperature of the gas
Answer to Problem 55A
The volume of helium gas is used in the filling of the balloon is
Explanation of Solution
Given information:
Temperature =
Initial pressure,
Final pressure,
Now, based on this result
The pressure is reduced from
Now, according to ideal
The gas has expanded to the volume
According to the calculation, the pressure is reduced to
So, the volume of helium gas which is used in filling the balloons is 187.886L.
Hence, the numbers of filled balloons are calculated as:
On the basis of the remaining volume of the helium in the tank, the filled balloons are
