不过用的场合不同. 1 MOLE的MOLECULE(SIMPLE MOLECULAR STRUCTURE)相对于1 MOLE CARBON-12 ATOM质量就可以用这个(同样是没有单位 因为相对) FORMULA MASS就是指1 MOLE的IONIC COMPOUND(GIANT IONIC STRUCTURE)的质量 单位是gmol^-1 MOLAR MASS就是指某ELEMENT的1 MOLE ATOM的质量 单位是gmol^-1 好啦...
3.8: Formula Mass and Mole Concepts of Compounds Formula Mass of Covalent Compounds Chemical formulas represent the elemental makeup of substances. For covalent compounds, the formula represents the numbers and types of atoms composing a single molecule of the substance; therefore, the formula mass...
Molar mass is calculated as a total of the atomic masses of all atoms that are present in a given compound. The atomic masses can be found in the periodic table. What is the formula to find molar mass? The molar mass is calculated as the product of mass and moles. Molar mass = Ma...
Learn about molecular mass. Understand what the formula unit mass is, how to find molecular mass, and exercise calculating molecular mass in some...
Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calcul
Fomula mass and molecular mass are two values that express the size of a molecule. Do you know the difference between formula mass and molecular mass? Theformula mass(formula weight) of a molecule is the sum of the atomic weights of the atoms in its empirical formula. ...
Molecular weight, mass of a molecule of a substance, based on 12 as the atomic weight of carbon-12. It is calculated in practice by summing the atomic weights of the atoms making up the substance’s molecular formula. The molecular weight of a hydrogen m
Because the definitions of both the mole and the atomic mass unit are based on the same reference substance,12C,the molar mass of any substance is numerically equivalent to its atomic or formula weight in amu. Per the amu definition, a single12C atom weighs 12 amu (its atomic mass is 12...

The molar mass of a compound defines the mass of 1 mole of that particular substance and number of grams per mole of a compound. Molar mass can be calculated if the number of atoms and the atomic weight of the element is known.
