Answer : The enthalpy change is, 7.205 KJ
Solution :
The conversions involved in this process are :
Now we have to calculate the enthalpy change.
where,
m = mass of water = 10 g
n = number of moles of water =![\frac{\text{Mass of water}}{\text{Molar mass of water}}=\frac{10g}{18g/mole}=\frac{10}{18}mole](/tpl/images/0137/4660/12279.png)
Now put all the given values in the above expression, we get
Therefore, the enthalpy change is, 7.205 KJ
