In an Experiment, 74

question 83

Multiple Choice

In an experiment, 74.3 g of metallic copper was heated to 100.0C and then quickly dropped into 200.0 mL of water in a calorimeter. The heat capacity of the calorimeter with the water was 875 J/C. The initial temperature of the calorimeter was 27.5C, and the final temperature after addition of the metal was 29.8C. What is the value of the molar heat capacity of copper?

• A)4.18 J/(mol   C)
• B)8.17 J/(mol   C)
• C)49.0 J/(mol   C)
• D)12.3 J/(mol   C)
• E)24.5 J/(mol   C)
