The mole contain a number of atoms equal to number of atoms in 12 g of carbon-12.
The Atomic Mass unit is equal to one-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
When isotopes are considered, they have the same atomic number but differed mass numbers.
The atomic mass, in grams, is the mass of one mole of atoms.
The true statements are A and B. Statement A is called Avogadro's number and represents the number of particles in one mole. Statement B refers to the molar mass, which is the mass of 1 mole of a substance expressed in grams, and is numerically equal to the atomic mass in atomic mass units (amu).
No, molar mass is the mass in grams of one mole of a substance. One mole is equal to the molecular weight of the substance in grams.
The average atomic mass of an element is the weighted average mass of an atom (including all its isotopes). This is related to the molar mass, because molar mass is the weight of 1 mole of something (atoms, molecules, etc...). 1 mole = 6.022 x10^23 = avogardro's constant.
When isotopes are considered, they have the same atomic number but differed mass numbers.
The element's average atomic mass.
The mass of a mole of a substance expressed in grams is called the molar mass. This value is numerically equal to the atomic or molecular weight of the substance and is expressed in units of grams per mole.
The atomic mass, in grams, is the mass of one mole of atoms.
The molar mass of a substance is the mass of one mole of that substance, measured in atomic mass units (amu) or grams per mole.

The molar mass of a substance is the mass of one mole of that substance, measured in grams per mole (g/mol) or atomic mass units (amu).
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 .
No, molar mass is the mass of one mole of a substance, expressed in grams per mole. Atomic number is the number of protons in the nucleus of an atom. Molar mass takes into account the mass of all the protons, neutrons, and electrons in a mole of a substance.
The molar mass of a substance is the mass of one mole of that substance, measured in grams per mole (g/mol). It is also expressed in atomic mass units (amu).
The true statements are A and B. Statement A is called Avogadro's number and represents the number of particles in one mole. Statement B refers to the molar mass, which is the mass of 1 mole of a substance expressed in grams, and is numerically equal to the atomic mass in atomic mass units (amu).
