STANDARD Physics Ideal Gas Equation MCQ Question

Type: MCQ-numerical-Medium-Class 11

A vessel has 6 g of oxygen at pressure P and temperature 400 K. A small hole is made in it so that oxygen leaks out. How much oxygen leaks out if the final pressure is P2\frac{P}{2} and temperature 300 K?

A

5 g

B

4 g

C

2 g

D

3 g

Correct Answer

Option C

Detailed Explanation

Using the ideal gas equation and the given conditions, we find that the mass of oxygen remaining is 4 g. Therefore, the mass of oxygen leaked is 6 g - 4 g = 2 g.
