Because Atomic Mass is the sum of both atomic number and number of neutrons in an atom.
The atomic number, which represents only the number of protons in the atom, does not take into account the number, and therefore the mass, of the atom's neutrons. (Nor the electrons, for that matter, but they are not considered to have weight.) Therefore there is only a loose relationship between atomic number and atomic mass or molar mass. And to complicate things further, atoms of the same element can exist in forms called isotopes, which, although possessing the same number of protons, have different numbers of neutrons, and therefore different mass.
Alcohol does not have an atomic number because it is not an element. Its molar mass is 46.07 g mol−1.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Molar mass is the weight of one mole of any chemical compounds. Atomic mass is the weight of just 1 atom of a compound
The molar mass is the mass of a molecule - sum of the masses of contained atoms, expressed in grams.The atomic mass is the mass of an isotope expressed in unified mass atomic units.The atomic weight is the mass of a chemical element (taking into account its isotopes) expressed in unified mass atomic units; also known today as relative atomic mass. IUPAC maintain the term (standard) atomic weight.
take the atomic number of Carbon, Hydrogen, and Oxygen and add them up. Molar Mass.
no youre thinking of molar mass and atomic weight although you use avogadro's number to find molar mass
Alcohol does not have an atomic number because it is not an element. Its molar mass is 46.07 g mol−1.
The atomic (molecular) weight of a substance is its molar mass.
The atomic number.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
the Atomic Mass in g/ml is the molar mass of the element
Molar mass is the weight of one mole of any chemical compounds. Atomic mass is the weight of just 1 atom of a compound

IUPAC maintain the term (standard) atomic weight.
molar mass is the atomic mass of the element. it's on the Periodic Table. you just have to add them up. unless you want to calculate the number of moles in a compound, in that case: moles = mass/molar mass
take the atomic number of Carbon, Hydrogen, and Oxygen and add them up. Molar Mass.
The molar mass of H2Te = 129.61588 g/mol
Molar mass is the mass of particles in one mole of a substance. Molar mass is equal to atomic/ molecular/ formula mass in amu. Formula mass is in atomic mass unit while molar mass is in grams .
