Atomic mass and molar mass are similar concepts but not the same. Atomic mass refers to the average mass of an atom of an element, while molar mass is the mass of one mole of a substance. The mass number of particles can be the same in certain cases, such as isotopes of the same element which have the same number of protons and different numbers of neutrons.
Yes, the molar mass is different for isoelectronic molecules.
When isotopes are considered, they have the same atomic number but differed mass numbers.
The atomic mass is the mass of an atom at rest. This refers to one atom, and is typically measured in so-called atomic mass units, and describes a single isotope of that element. The atomic weight is the abundance-weighted average mass of an element (an average mass of all the isotopes that exist for that element, weighted by how abundant each isotope is in nature). Atomic weight is commonly reported in atomic mass units, as well as in grams per mole. The molar mass is the mass of one mole of something, and can refer to both a single element as well as molecules and other compounds. The molecular weight is essentially the same thing as the molar mass except that, as the name implies, it refers to molecules rather than just elements. The molar mass and molecular weight is typically given in units of grams per mole.The molecular weight of a compound is found by adding the atomic weights of all of the atoms in the compound. Water, for example, has a molecular weight of 18.0152 grams/mole, as there are two hydrogen atoms that each have an atomic weight of 1.00079 g/mole and one oxygen atom with an atomic weight 15.9994 grams/mole.
A mole is the amount of a substance that contains as many atoms, molecules, ions, or other elementary units as the number of atoms in 0.012 kilogram of carbon 12. The number is 6.0225 × 1023, or Avogadro's number. Molar mass is the mass of one mole of a substance.

no youre thinking of molar mass and atomic weight although you use avogadro's number to find molar mass
It means that atomic weight is expressed in form of Molar weight. When we write that the atomic mass of an element is X, it means that it is X amu(atomic mass unit) and not X grams. An atomic mass unit is very less as compared to a gram. The molar mass of an element or compound is its same mass as in amu but in grams.
Yes, molecular weight and molar mass are essentially the same concept in chemistry. They both refer to the mass of a molecule or compound, expressed in atomic mass units or grams per mole.
The element's average atomic mass.
No, Dalton is a unit of atomic mass, while g/mol is a unit of molar mass.
When isotopes are considered, they have the same atomic number but differed mass numbers.
Molar mass of an element is the atomic weight on the periodic table in grams. 1 mole of atoms of an element is 6.022 x 1023 atoms. To find the mass of one atom of an element, divide the element's molar mass by 6.022 x 1023 atoms.Example:Sodium, Na, has a molar mass of 22.989770g/mol (atomic weight in grams)1 mole Na atoms = 6.022 x 1023 atomsSolution:22.989770g/mol x 1mol/6.022 x 1023 atoms = 3.818 x 10-23g/atom

Molecular oxygen will effuse faster because: Molar Mass of O2: 32g Atomic Mass of Ar: 40g
No: They have the same atomic number but not the same atomic mass.
