Question
a metal sample weighing 45.0g and at a temperature of 99.1C was place in 38.6g of water in a calorimeter at 25.0C. the calorimeter reached a maximum temperature of 32.8C.
1. calculate the specific heat of the metal.
2. what is the approximate molar mass of the metal?

Answers
1) [mass metal x specific heat metal x Tfinal-Tinitial)] + [mass H2O x speicif heat water x (Tfinal-Tinitial) = 0
Only one unknown, specific heat metal. Solve for that.
2)Use the Law of Dulong and Petit
