what is the difference between atomic molar mass and molar mass?
70682
Molar mass is the mass of one mole of a substance. Atomic mass is the mass of one individual unit of a substance. the atomic mass in amu of a substance is numerically equivalent to the mass in g of one mole of that substance.

The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.

The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol). Although mass can be expressed as both amu and g/mol, g/mol is the most useful system of units for laboratory chemistry.

In chemistry the substance is usually measured using molecular mass and molar mass. ... Expression of molar mass is grams per mole. It can also be expressed as kilogram per mole. Molecular mass is expressed in atomic mass units.

Explanation: 1 atomic mass unit (a.m.u.) is the mass of a proton or a neutron which is equal to 1.6726219×10−27kg . which is close to the mass that you find in a periodic table.

That is, the molar mass of a substance is the mass (in grams per mole) of 6.022 × 1023 atoms, molecules, or formula units of that substance.

Atomic mass is also known as atomic weight. Atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that element's isotopes. The mass number is a count of the total number of protons and neutrons in an atom's nucleus.

Explanation: When we write "formula mass", we usually mean the mass associated with 1 mole of such a formula; i.e. Avogadro's number of such a formula. Molar mass is the same thing: Avogadro's number of whatever stuff you have.

Molar mass expressed in grams is called moles. So simply you can find out moles of any element by knowing its molar mass. eg: molar mass of H is 2 hence 1 mole of H contains 2 atoms/particles. In H2O hydrogen have 2 mole.

According to the definitions given, atomic mass which is also called atomic weight is the measured total mass of an element's atom. Whereas, atomic number is nothing but the total number of neutrons and protons in the nucleus of an atom.

The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol). The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.

Atomic mass (ma) is the mass of an atom. A single atom has a set number of protons and neutrons, so the mass is unequivocal (won't change) and is the sum of the number of protons and neutrons in the atom. ... Atomic weight is a weighted average of the mass of all the atoms of an element, based on the abundance of isotopes.

Molecular weight is the mass of one molecule of a compound, while molar mass is the mass of one mole of a compound.

Answer: Actual mass of a molecule is obtained by dividing the molar mass by Avogadro's number whereas gram molecular mass represents the molecular mass expressed in grams, i.e., it is the mass of 1 mole of molecules, i.e., Avogadro's number of molecules.

Mass number. The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.

While the mass number is the sum of the protons and neutrons in an atom, the atomic number is only the number of protons. The atomic number is the value found associated with an element on the periodic table because it is the key to the element's identity.
