question 8

Multiple Choice

In an experiment,138 g of graphite is heated to 90.0°C and then quickly transferred to 150.0 g of water in a calorimeter at 25.0°C.The heat capacity of the calorimeter with the water is 157 J/°C.The final temperature comes to 50.0°C.What is the approximate specific heat capacity of graphite? [c_p(water) = 4.18 J/(g . °C) ]

• A)0.711 J/(g . °C)
• B)0.615 J/(g . °C)
• C)0.493 J/(g . °C)
• D)1.85 J/(g . °C)
• E)4.51 J/(g . °C)
