Asample of nickel is heated to 99.8 degrees c and placed in a coffee cup calorimeter containing 150.0g water at 23.5 degrees c. after the metal cools, the final temperature of metal andwater mixture is 25.0 degrees c. if the specific heat capacity of nickel is 0.444j/(degreescg),
what mass of nickel was originally heated?
Answers: 3
![m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]](/tpl/images/0402/0900/09236.png)
.................(1)
= mass of water= 150.0 g
= mass of nickel = ?
= final temperature = 
= temperature of water = 
= temperature of nickel = 
= specific heat of water = 
= specific heat of nickel= 
![150.0\times 4.184\times (298-296.5)=-[m_2\times 0.444\times (298-372.8)]](/tpl/images/0402/0900/54914.png)
