NEET Physics Ideal Gas Equation MCQ Question
Consider a diagram showing a vessel containing a mixture of neon and oxygen gases at the same temperature and volume. If the partial pressure ratio of neon to oxygen is 3:2, what is the ratio of the number of moles of neon to oxygen?
3:2
1:1
2:3
5:3
Correct Answer
Detailed Explanation
According to the ideal gas equation, for gases at the same volume and temperature, the ratio of partial pressures equals the ratio of moles. Given P1/P2 = μ1/μ2 = 3/2, the ratio of moles of neon to oxygen is 3:2.
