In an Experiment, 74

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)
