Figure below. $230k\frac{g}{h}r$ of $K_{2}C{O}_3$ solution are heated by the air. Assume that the heat

exchanger has negligible heat losses. The terminal temperatures are given in Figure.

Calculate the $H(\frac{J}{m}ol)$ at $T_{\text{o}\text{u}\text{t}}$ for $H_{2}O.$

$H_{\text{a}\text{i}\text{r}}(at127C)=3696\frac{J}{m}ol$

$H_{\text{a}\text{i}\text{r}}(at227C)=6660\frac{J}{m}ol$

$H_{H20}(at27C)=111\mathrm{.}7\frac{J}{m}ol$
