A 93.7 g 5.20 mole sample of water is heated to exactly, Ask an Expert

Academics

A 93.7 g (5.20 mole) sample of water is heated to exactly 94.4 celsius. It is then added to 90.1 g (5.00 mole) of water at 22.5 celsius in a styrofoam cup calorimeter. The final temperature at equilibrium is 59.0 celsius. What is the calorimeter constant, if the measured temperature of the calorimeter only rises from 22.5 celsius to 31.5 celsius over this same period of time?
