366364 An ice cube of mass \(0.1Kg\) at \(0^\circ C\) is placed in an isolated container which is at \(227^\circ C\). The specific heat \(c\) of the container varies with temperature \(T\) according to the empirical relation \(c=A+B T\), where \(A = 100\,cal/Kg - K\) and \(B = 2 \times {10^{ - 2}}cal/Kg - {K^2}\). If the final temperature of the container is \(27^\circ C\), find the mass of the container. (Latent heat of fusion for water \( = 8 \times {10^4}cal/Kg\) specific heat of water \(\left. { = {{10}^3}cal/Kg - K} \right)\).
