1. The problem statement, all variables and given/known data
cold water: 50g
cold water temp: 22.23 C
hot water: 50 g
hot water temp: 63.2 C
final temp: 39.55 C
2. Relevant equations
3. The attempt at a solution
heat lost by hot water:
(4.18)(50)(39.55-63.22)=-4942.85
heat gained by cold water:
(4.18)(50)(39.55-22.23)=3619.88
heat gained by calorimeter:
-(-4942.85 J+3619.88 J)=1322.97 J
calorimeter constant:
1322.97/17.32=76.38
is this right? im especially not sure about the last one.
