If you look at the table of specific heat values for different
metals, they are all so different from one another. The difference
is mainly because specific heat is expressed as energy per unit
mass. If specific heat were given as energy per mole, the values
would be very similar. It is, in fact, this similarity of the molar
specific heats of metals, which is the basis for the Law of Dulong
and Petit. The law of Dulong and Petit states that the heat
capacity of a metal in J/ g⋅ oC multiplied by the molar mass of the
metal in grams/mole is a constant: Cp x Molar Mass = 25 J/mol⋅oC
Using the heat capacity value of 0.3867J/mol⋅oC , solve for the
molar mass of the metal. (Put your answer in 4 significant
figures)
Based on your calculations, which metal is this?
a-copper
b-iron
c-aluminum
d-lead
