**Chemistry Experiment: Coffee Cup Calorimetry**When a chemist dissolved a 12.7 g sample of potassium hydroxide (KOH) in 100.0 grams of water in a coffee cup calorimeter, the temperature of the water increased by 27.6°C. To calculate the heat energy required to dissolve the KOH sample, assume the specific heat capacity of the solution is 4.184 J/g°C.Firstly, calculate the heat absorbed (q) by the water using the formula:\[ q = m \cdot c \cdot \Delta T \]Where:- \( m \) is the mass of the water (100.0 g)- \( c \) is the specific heat capacity (4.184 J/g°C)- \( \Delta T \) is the change in temperature (27.6°C)Complete the calculation to find the value of \( q \) in kJ.Next, calculate the heat of solution for KOH in kJ/mol. For this calculation, consider the moles of KOH dissolved in the solution. Use the molar mass of KOH to convert grams to moles and complete the following calculation:\[ \text{Heat of solution (kJ/mol)} = \frac{q \text{ (kJ)}}{\text{moles of KOH}} \]**Graph/Diagram Explanation:**There are no graphs or diagrams in this document. Instead, there are two calculations to be completed to find the values of heat absorbed and the heat of solution. Rectangular boxes are provided for entering the calculated values for \( q \) in kJ, and for the heat of solution in kJ/mol.
