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)

What is the specific heat of thorium?
The molar heat capacity of thorium is 26,230 J/mol.K.
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.
What is the relation between Heat capacity and specific heat?
specific heat is directly proportional to heat capacity
Dimensional formula for heat capacity and specific heat capacity?
heat capacity- ML2T-2K-1 Specific Heat Capacity-M0L2T-2K-1
Why gases have two specific heat?
Gasses have two specific heat capacities because the boundary conditions can affect the number by up to 60%. Therefore, a number is given to each boundary condition: isobaric (constant pressure) or isochoric (constant volume). In an ideal gas, they differ by the quantity R (the gas constant - the same one you use in the ideal gas law): Cp = Cv + R where Cp is the isobaric molar heat capacity (specific heat) and Cv is the isochoric molar heat capacity.
How is molar heat capacity related to specific heat?
molar heat capacity is the product of specific heat capacity and molecular weight molar heat capacity=specific heat capacity*molecular weight
What is the molar heat capacity of liquid water?
Molar heat capacity of liquid water = 75.3538 Molar heat capacity = molar mass x specific heat
What is the heat capacity of 170 g of liquid water?
heat capacity= specific heat x mass molar heat capacity = specific heat x molar mass - Hope this helps!!
How does molar heat capacity differ from specific heat?
Molar specific heat capacity is the amount of heat energy required to raise thetemperature of 1 mole of a substance
What is the specific heat capacity for selenium?
The molar heat capacity of selenium is 25,363 J/mol.K.
What is the specific heat of thorium?
The molar heat capacity of thorium is 26,230 J/mol.K.
Molar heat capacity of water?
The Molar heat Capacity of water is 75.2
What is the difference in specific heat between hydrogen and oxygen molecules?
The molar heat capacity of hydrogen (H2) is 28,835 J/mol/K.The molar heat capacity of oxygen (O2) is 29,378 J/mol/K.
What is the specific heat capacity of Na2CO3?
Assuming molar heat capacity: 112.3 J/(mol K) (joules per mole kelvin difference)
What is another way to say heat capacity?
Another way of stating this, is that the volume-specific heat capacity (volumetric heat capacity) of solar elements is roughly constant. The molar volume of the solid.
Does aluminum have a higher specific heat capacity then lead?
no because the molar mass of lead is great than aluminum
