Answer:
![\Delta H=4.63x10^{5}J=463kJ](https://tex.z-dn.net/?f=%5CDelta%20H%3D4.63x10%5E%7B5%7DJ%3D463kJ)
Explanation:
Hello,
In this case, we find the following states:
a. Liquid salt water at 28.0 °C.
b. Liquid salt water at 102.5 °C.
c. Vapor salt water at 102.5 °C.
The first process (1) is to heat the liquid water from 28.0 °C to 102.5 °C and the second one (2) to vaporize the liquid salt water. In such a way, each process has an amount of energy that when added, yields the total energy for the process as shown below:
![\Delta H=\Delta H_1+\Delta H_2\\\Delta H=mCp\Delta T+m\Delta _VH\\\Delta H=175g*5.19\frac{J}{g*K}*(375.65K-301.15K)+175g*2.26\frac{kJ}{g} *\frac{1000J}{1kJ} \\\Delta H=4.63x10^{5}J=463kJ](https://tex.z-dn.net/?f=%5CDelta%20H%3D%5CDelta%20H_1%2B%5CDelta%20H_2%5C%5C%5CDelta%20H%3DmCp%5CDelta%20T%2Bm%5CDelta%20_VH%5C%5C%5CDelta%20H%3D175g%2A5.19%5Cfrac%7BJ%7D%7Bg%2AK%7D%2A%28375.65K-301.15K%29%2B175g%2A2.26%5Cfrac%7BkJ%7D%7Bg%7D%20%2A%5Cfrac%7B1000J%7D%7B1kJ%7D%20%5C%5C%5CDelta%20H%3D4.63x10%5E%7B5%7DJ%3D463kJ)
