Please help me to find the enthalpy change, the heat (q) absorbed and the calorimeter constant

\begin{tabular}{|l|l|} \hline Volume of deionized water, cold & 98.184ml \\ \hline Temperature, cold water (T initial) & 23.0C \\ \hline Volume of deionized water, hot & 96.469ml I \\ \hline Temperature, hot water & 64.18C \\ \hline Final temperature (Tmix) & 41.1C \\ \hline Net temperature change, cold water & 18.1C \\ \hline Net temperature change, hot water & 23.08C \\ \hline Enthalpy change, cold water, q cold (j) & \\ \hline Enthalpy change, hot water, q hot (J) & \\ \hline Temperature change, calorimeter & 18.1C \\ \hline \end{tabular}
