In an Experiment, 138 G of Graphite Is Heated to 90.C

question 169

Multiple Choice

In an experiment, 138 g of graphite is heated to 90.0C and then quickly transferred to 150.0 g of water in a calorimeter at 25.011eed8b2_2d82_a951_a0ba_55ddc23a4114_TB6562_11C.The heat capacity of the calorimeter with the water is 157 J/11eed8b2_2d82_a951_a0ba_55ddc23a4114_TB6562_11C.The final temperature comes to 50.011eed8b2_2d82_a951_a0ba_55ddc23a4114_TB6562_11C.What is the approximate specific heat capacity of graphite?
[c_p(water) = 4.18 J/(g .11eed8b2_2d82_a951_a0ba_55ddc23a4114_TB6562_11C) ]

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