Calculate the Calorimeter Constant if 25 g of water at 58C was added to 25 g of water at 25C with a resulting temperature of 35C?

1 answer

The sum all heats gained is zero.

masshotwater*cw*deltaTemp + masscoldwater*cw*deltaTempc +Constant*deltaTempc=0

25*cw(35-58)+35(cw)(35-25)+K(35-25)=0
calculate K
