A) more in the He filled balloon
B) same in both balloons
C) more in air filled balloon
D) in the ratio of 1 : 4
Correct Answer: B
Solution :
Ideal gas equation can be written as \[PV=nRT\] ?(i) In this equation, n = number of moles of the gas P = pressure of the gas V = volume of the gas R = universal gas constant and T = temperature of the gas From Eq. (i), we have\[\frac{n}{V}=\frac{P}{RT}=\text{constant}\] So, at constant pressure and temperature, both balloons will contain equal number of molecules per unit volume.
