The mole unit measures what variable
Webg/mol. In chemistry, the molar mass ( M) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of said compound. [1] The molar mass is a bulk, not molecular, property of a substance. The molar mass is an average of many instances of the compound, which often vary in mass ... WebHeat capacity is the amount of heat required to change the temperature of a given amount of matter by 1°C. The heat capacity of 1 gram of a substance is called its specific heat capacity (or specific heat), while the heat capacity of 1 mole of a substance is called its molar heat capacity.
