Three flasks of equal volumes contain CH 4 , CO 2 & Cl 2 gases respectively. They will contain equal number of molecules if
Options
- AThe mass of all the gases is same
- BThe mass of all the gases is same but Temperature is different
- CTemperature & Pressure of all the flasks are same
- DTemperature, Pressure & Masses same in the flasks
Correct answer
C. Temperature & Pressure of all the flasks are same
Step-by-step solution
According to the ideal gas equation, The number of molecules is equal when the number of moles are equal. Ideal gas equation is PV = nRT If volume is equal then the temperature and pressure also equal for the equal number of moles. Hence, they will contain equal number of molecules if temperature & Pressure of all the flasks are same.
