A group of students place 15.41g of a metal into a test tube. They place the test tube into a beaker of boiling water until the temperature of the metal was 89.8°C. Then they quickly place the heated metal into a beaker of 10.47g of water with an initial temperature of 16.4°C. The temperature of the mixture came to rest at 26.1°C. What is the specific heat of the metal used? (CH2O = 4.18 J/g°C)
