Specific heat is the heat capacity divided by the heat capacity of water, which makes it dimensionless. To obtain molar heat capacity from specific heat for a material of interest, simply multiply the specific heat by the heat capacity of water per gram [1 cal/(g*C)]and multiply by the molecular weight of the substance of interest.

For example, to obtain the molar heat capacity of iron

Specific heat of iron = 0.15 (note there are no units)

Molar heat capacity of iron = 0.15*1 cal/(g*C)*55.85 g /gmole

= 8.378 cal/(gmole*C)

no because the molar mass of lead is great than aluminum

By what quantity must the heat capacity of an object be divided to obtain the specific heat of that material?

Heat capacity is in the measurement of (kilo)Joules per mol degree Kelvin (J/mol K) Specific heat capacity is in joules/gram degree Kelvin (J/ gram K) Converting between the two is rather simple. To convert to specific heat capacity, divide the molar heat capacity by the molar mass of the molecule in question. eg. ( J/ mol K) / (grams/mol ) = J/ gram K, because mols will cancel.
