Assertion: At constant temperature, if pressure on the gas is doubled, density is also doubled.
Reason: At constant temperature, molecular mass of a gas is directly proportional to the density and inversely proportional to the pressure

Options

A. If both (`A`) and (`R`) are correct and (`R`) is the correct explanation of (`A`).
B. If both (`A`) and (`R`) are correct, but (`R`) is not the correct explanation of (`A`).
C. If (`A`) is correct, but (`R`) is incorrect.
D. If (`A`) is incorrect, but (`R`) is correct.

Answer

A, B, C, D

Explanation

Molecular mass does not depend upon `T`, `P`.
