Question

2.
State Dulong Petit's law. Describe how the atomic mass of an element is determined by
the use of the law. A certain metal oxide contains 60% of oxygen. The specific heat of
the metal is 0.401. Calculate the exact atomic mass, equivalent mass and valency of the
metal.
3. State and explain Dulong and Petit's law. The choloride of a metal M contains 23.2%
of metal. Its specific heat is 0.224. What is the accurate atomic mass of the metal ?
