A block of ice of mass \( 120 \mathrm{~g} \) at temperature \( 0^{\circ} \mathrm{C} \) is put in 300 gm of water at \( 25^{\circ} \mathrm{C} \). The \( x g \) of ice melts as the temperature of the water reaches \( 0^{\circ} \mathrm{C} \). The value of \( x \) is
[Use: Specific heat capacity of water \( =4200 \mathrm{Jkg}^{-1} \mathrm{~K}^{-1} \). Latent heat of ice \( =3.5 \times 10^{5} \mathrm{Jkg}^{-1} \) )
