Answer:
The specific heat of the unknown metal is 1.26*10⁻⁴ 
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat occurs when heat added or removed from a substance causes a temperature change in it and is calculated by:
Q = c * m * ΔT
Where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c and where ΔT (Tfinal - Tinitial) is the variation in temperature
In this case:
- Q= 2.93 kcal
- c= ?
- m= 183.4 g
- ΔT= 126.3 °C
Replacing:
2.93 kcal= c* 183.4 g*126.3 °C
Solving:

c= 1.26*10⁻⁴

Explanation:
Density can be calculated using the following rule:
density = mass / volume
Therefore,
volume = mass / density
For diamond:
we have mass = 0.5 grams and density = 3.51 g / cm^3
Substituting in the rule, we can calculate the volume of diamond as follows:
volume = 0.5 / 3.51 = 0.14245 cm^3
For graphite:
we have mass = 0.5 grams and density = 2.25 g / cm^3
Substituting in the rule, we can calculate the volume of graphite as follows:
volume = 0.5 / 2.25 = 0.2223 cm^3
