A 5.00g sample of an unknown metal at an initial temperature of 78.3 C was dropped into the calorimeter.

The final temperature of mixture was 46.3 C.

Calculate the specific heat of the metal. The specific heat of ater is 4.184 J/ (g C)?

**Devron**, Tuesday, March 19, 2013 at 9:04pmYou will need the following equation:

q=mc∆T

heat lost=heat gain, that is,

m1c1∆T1=m2c2∆T2

Where

m1=25.0g

c1=4.184 J/ (g C)

∆T1=46.3ºC-78.3º C=32.0ºC

m2=5.00g

c2=?

∆T2=46.3ºC-23.8ºC=22.5

Solve for c2,

c2=m1c1∆T1/m2∆T2
