Question

The density of a gas \(X\) is twice that of another gas \(Y\). If the molecular weight of gas \(Y\) is \(M\), then the molecular weight of the gas \(X\) will be

• A. \(2M\)
• B. \(\frac{M}{2}\)
• C. \(M\)
• D. \(\frac{M}{4}\)

Hint:

At same temperature and pressure, gas density is proportional to molecular weight: \(\rho\propto M\).

Answer 1

The Correct Option is A
