The atomic mass of a mole?
When isotopes are considered, they have the same atomic number but differed mass numbers.
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 answer depends on the composition of the molecule.
What does atomic mass number tell us?
Type your answer here..The Atomic Mass Unit tells us that ,How heavy a substance as compare to the other.
How is a mole related to the atomic mass?
The atomic mass, in grams, is the mass of one mole of atoms.
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 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.
Using the periodic table what is the mass of 2 moles of copper?
The relative atomic mass of an element is the mass in grams of 1mole of the substance. The relative atomic mass of copper is 63.5 2x63.5 = 127g
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.
