¡Hola!
En este caso, dado que el pH de una solución se entiende como el potencial de los iones hidrógeno en la misma, es posible recordar la ecuación que se usa para calcularlo:
De este modo, al conocer el pH, se resuelve para la concentración de iones hidrógeno como se muestra a continuación:
Así, reemplazamos el pH para obtener:

The total heat of a process is the sum of all the heat involved in the process. So, the total heat is the sum of all sensible and latent heat in the whole process. For this case, the flow of the release of heat is,
sensible heat from 400 K to the boiling point (351 K) ---> latent heat due to condensation ------> sensible heat from 351 K to melting point (159 K) -----> latent heat due to freezing --------> sensible heat from 159 K to 100 K
Total heat released = 87.53 J/(mol•K)<span> (400 K - 351 K) + </span><span>38560 J/mol + </span><span>112.4 J/(mol•K) ( 351 K - 159 K ) + </span>4900 J/mol + 111.46J / (mol•K) ( 159 K - 100 K) = 75905.91 J / mol
