When 2 g of a gas A is introduced into an evacuated flask kept at 25� – InterviewSolution

1.	When 2 g of a gas A is introduced into an evacuated flask kept at 25∘C, the pressure is found to be 1 atm. If 3 g of another gas B is then added to the same flask at the same temperature, the total pressure becomes 1.5 atm. Assuming ideal gas behaviour, the value of MBMAto the nearest integer is :
Answer» When $2 g$ of a gas A is introduced into an evacuated flask kept at $25^{\circ} C$ , the pressure is found to be $1 a t m$ . If $3 g$ of another gas B is then added to the same flask at the same temperature, the total pressure becomes $1.5 a t m$ . Assuming ideal gas behaviour, the value of $\frac{M_{B}}{M_{A}}$ to the nearest integer is :
