हिन्दीA vessel of volume \( V \) contains a mixture of 1 mole of Neon (atomic mass \( 20\text{ u} \)) and 2 moles of Oxygen (molecular mass \( 32\text{ u} \)) at temperature \( T \). Assuming ideal gas behaviour, what is the ratio of the partial pressure of Neon to the total pressure of the mixture?
View Answer & Solution
Correct answer · Option D
\( 1 : 3 \)
Explanation
By Dalton's law of partial pressures, \( P_{\text{Ne}} = \frac{\mu_1 RT}{V} \) and \( P_{\text{total}} = \frac{(\mu_1 + \mu_2) RT}{V} \). Thus, \( \frac{P_{\text{Ne}}}{P_{\text{total}}} = \frac{\mu_1}{\mu_1 + \mu_2} = \frac{1}{1 + 2} = \frac{1}{3} \).
