A thermally insulated vessel contains 150g of water at \[0{}^\circ C\]. Then the air from the vessel is pumped out adiabatically. A fraction of water turns into ice and the rest evaporates at \[0{}^\circ C\] itself. The mass of evaporated water will be closest to: (Latent heat of vaporization of water \[=2.10\times {{10}^{6}}Jk{{g}^{1}}\] and Latent heat of Fusion of water \[=3.36\times {{10}^{5}}Jk{{g}^{1}}\])                           [JEE Main 8-4-2019 Morning]
