Two vessels A and B contain same mass of Oxygen and Hydrogen respectively at the same temperature. The volume of B is twice that of A. The ratio of gas pressure in A to that in B is
- A \(1:64\)
- B \(1:8\)
- C \(1:256\)
- D \(1:32\)
Answer & Solution
Correct Answer
(B) \(1:8\)
Step-by-step Solution
Detailed explanation
Using the ideal gas equation, \(PV = nRT = \dfrac{m}{M}RT\), where \(m\) is the given mass and \(M\) is the molar mass. For vessel A containing Oxygen (\(O_2\), \(M_A = 32\)): \(P_A = \dfrac{mRT}{32 V_A}\) For vessel B containing Hydrogen (\(H_2\), \(M_B = 2\)):…
