What is molar atomic mass?

The atomic (molecular) weight of a substance is its molar mass.


What is the atomic mass for oxide?

It doesn't have an Atomic Mass, it is not an element (pure substance) it is a compound and therefore only has a molar mass.


What the molecular mass of MgF2?

The Atomic Mass of Mg is 24. The atomic mass of fluorine is 19. Therefore the relative mass of the substance is 62.


What is the atomic mass of 25mg?

The atomic mass of a substance is the mass of one mole of that substance. To calculate the atomic mass of 25 mg of a specific element, you would first need to determine the molar mass of that element. You can then use the molar mass to convert the mass of the sample (25 mg) to the number of moles, and then calculate the atomic mass of that amount.


Why is the average atomic mass used when calculating grams of a substance?

the elements in the substance are mixtures of their isotopes


What is the mass of one molecule of a nonionic substance in atomic mass units?

The mass of one molecule of a nonionic substance in atomic mass units can be determined by adding up the atomic masses of all the atoms it contains. This can be found by looking up the atomic masses of each element on the periodic table and summing them together.


How is a mole related to the atomic mass?

The atomic mass, in grams, is the mass of one mole of atoms.


What is the gram atomic mass?

The gram atomic mass, also known as molar mass, is the mass of one mole of an element or a compound in grams. It is numerically equal to the atomic or molecular weight of the substance in atomic mass units.


What is the difference between a substance's atomic number and it's atomic mass?

Atomic number defines as how many nmbr of electrons and protons d atom contain. No. of electron=No. of protons=Atomic Nmbr. Atomic mass defines d mass of total protons and neutrons(mass of nucleus) of an atom.


How many atomic mass unit 1 gram of a substance have?

1 atomic mass unit is 1.660538921(73)×10−27 kg. 1 gram contain 0,6022.1024 atomic mass units.


What is relationship between atomic mass and average atomic mass?

The average atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. It is, the mass of an atom of the substance, rescaled so that carbon-12 would have a mass of 12.


What does atomic mass do?

Atomic mass represents the total mass of the protons and neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and is used to calculate the average mass of all the isotopes of an element. Atomic mass also helps in determining the molar mass of a substance, which is crucial for stoichiometry calculations in chemistry.
