Sources of pollution can be natural, but they are often human-related.
Sources of pollution include dirt, bacteria, and fertilizers.
There are multiple factors that contribute to the cost of a mineral.
First of all is the demand or application, which will be related to its
physical properties. For example, nontarnishing metals like gold are
held in high value for their appearance. Second is the supply of the
mineral, those that only have a small quantity in the earth's crust are
likely to be more expensive. Third is the cost of extraction and
manufacturing. Some minerals may be abundantly found, but may be
distributed over a wide area, meaning that it is still expensive to mine
and transport.

<h2>Answer:</h2>
<em>8.67kJ/mol</em>
<h2>Explanations</h2>
The formula for calculating the amount of heat absorbed by the water is given as:
Determine the moles of KI
Since heat is lost, hence the enthalpy change of the solution will be negative that is:
Determine the enthalpy of solution in kJ•mol-1
Hence the enthalpy of solution in kJ•mol-1 for KI is 8.67kJ/mol
