What is the approximate molar mass of Y? Question: The edge of a body-centered-cubic unit cell of an element Y was found to be 网页Molar mass of a metal by measuring its specific heat capacity Asynchronous Lab Instructions Dulong and Petit’s law states that specific heat capacity x atomic mass = 3R 网页David Park. First, you can calculate the molar mass of FeCl2 by adding the molar masses of Fe (55.845 g/mol) and 2 atoms of Cl (2 times (35.446 g/mol). This gives a molar mass of 126.737 g/mol. Since each mole is 126.737 grams, you multiply 3.5 mols by 126.737 grams, giving you 443.58 grams. 网页Molecular mass or molar mass are used in stoichiometry calculations in chemistry. In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu". 网页2021年3月20日 The Dulong-Petit Law is normally expressed in terms of the specific heat capacity () and the molar mass () of the metal. where represents how much heat is required to raise the temperature of 'one gram' of that substance by one degree Kelvin.
