What is the molar mass of a substance

So the molar mass of a chemical compound is defined as the mass of a sample of that compound is divided by the amount of the substance in that sample measured in the moles.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
