5. To determine whether a shiny silver-colored rock is actually silver, a chemistry student decides to measure its heat capacity. She first weighs the rock and finds it has a mass of 9.87 g. She then finds that upon absorption of 42.4 J of heat, the temperature of the rock rises from 54 °C to 76 °C. Find the specific heat of the object and determine if it matches the specific heat of real silver. (CAg = 0.239 J/g°C)
