    A vessel is filled with a gas at a pressure of 76 cm of mercury at a certain temperature. The mass of the gas is increased by \[50\,%\] by introducing more gas in the vessel at the same temperature. The resultant pressure, in cm of Hg, is-

    A) 76                                

    B) 152

    C) 114                              

    D) 1117

    Correct Answer: C

    Solution :

    \[P\propto m\] Since m is increased by a factor of \[\frac{3}{2}\], therefore, P will increase by a factor of \[\frac{3}{2}\]. \[\therefore \,\,\text{ }New\text{ }pressure=\frac{3}{2}\times 76\text{ }cm\text{ }of\text{ }Hg\] \[=\text{ }114\text{ }cm\text{ }of\text{ }Hg.\]
