when 5.0g of KOH is added to 100mL of water , the temperature of the solution increases by 3 degree Celsius . assume the density of the solution to be 1g/mL and specific heat capacity of the solution to be 4.184 J/g K.
1 ) calculate the amount of heat absorbed by the solution
2 ) find the enthalpy change for the dissolution of KOH
3) find the enthalpy change per mole of KOH
