Answer:


\Delta T=0.160\°C

Step-by-step explanation:

Hello there!

In this case, according to the following equation for the calculation of heat in this calorimetry problem:


Q=mC\Delta T

It is possible for us to calculate to calculate the change in temperature for this process by solving for DT in the aforementioned equation:


\Delta T=(Q)/(mC)\\\\ \Delta T=(125.7cal)/(634.5g*1.241 cal/(g\°C)) \\\\ \Delta T=0.160\°C

Best regards!
