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 capacity for selenium?
The molar heat capacity of selenium is 25,363 J/mol.K.
How can you measure the molar heat of solution of solids?
The molar heat of solution of a solid can be measured by dissolving a known mass of the solid in a specific amount of solvent and measuring the temperature change that occurs. By using the formula q = mcΔT (where q is heat energy, m is mass, c is specific heat capacity, and ΔT is temperature change), the molar heat of solution can be calculated.
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.
What is the heat capacity of 165g of liquid water?
The specific heat capacity of liquid water is 4.184 J/g°C. To find the heat capacity, you multiply the mass of the water (165g) by the specific heat capacity. So, the heat capacity of 165g of liquid water is 688.56 J/°C.
What is approximately the molar heat capacity of most metals?
The molar heat capacity of most metals is approximately 25 J/mol·K. This means that it takes about 25 Joules of energy to raise the temperature of 1 mole of a metal by 1 Kelvin.
What is molar heat?
Different substances have varied molar heat capacities. The molar heat capacity of a substance refers to the amount of heat energy needed to raise 1 mole of that substance by 1 degree Celsius.
Molar heat capacity of water?
Molar heat capacity of liquid water = 75.3538 Molar heat capacity = molar mass x specific heat
Is molar heat capacity intensive or extensive?
Molar heat capacity is an extensive property because it depends on the amount of substance being considered.

The molar heat capacity of selenium is 25,363 J/mol.K.
What is the symbol for molar heat capacity and how is it calculated?
The symbol for molar heat capacity is (Ctextm). It is calculated by dividing the heat capacity of a substance by the amount of substance in moles. Mathematically, it is expressed as (Ctextm fracCn), where (C) is the heat capacity and (n) is the amount of substance in moles.
How do you prove that the molar heat capacity at the constant volume?
no be quiet

The molar heat capacity of gaseous hexane at 25 degrees Celsius is 142.6 J What is the specific heat?
Specific heat capacity is an intrinsic property of a substance and is independent of the amount of the substance. Therefore, the specific heat capacity of gaseous hexane would be the same as its molar heat capacity, which is 142.6 J/mol°C.
How can one determine the molar enthalpy of a reaction?
To determine the molar enthalpy of a reaction, one can measure the heat released or absorbed during the reaction using a calorimeter. By knowing the amount of reactants used and the temperature change, the molar enthalpy can be calculated using the formula q mCT, where q is the heat exchanged, m is the mass of the substance, C is the specific heat capacity, and T is the temperature change.
