Answer:
A. No; B. yes
Explanation:
A. Mass
The balloons contain different gases, which will have different densities.
Mass = volume × density
m = V × D
However, the volume is the same for all three balloons.
Thus m = kD
And the mass of the gas is directly proportional to the density.
Since the density varies, the mass varies.
B. Number of molecules
This is Avogadro's Hypothesis:
At the same conditions of temperature, equal volumes of gases contain the same number of molecules.
Answer:
The value of 
at 4224 K is 314.23.
Explanation:
Initially
4.97 atm 0
At equilibrium
4.97 - p 2p
At initial stage, the partial pressure of oxygen gas = =4.97 atm
At equilibrium, the partial pressure of oxygen gas = 
So, 4.97 - p = 0.28 atm
p = 4.69 atm
At equilibrium, the partial pressure of O gas = 
The expression of is given as :
The value of at 4224 K is 314.23.
