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 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?

What is the molar mass of a substance in amu grams per mole?
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.
What is the molar mass of the substance in amug/mol?
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).
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 many moles of a substance with an atomic mass unit (amu) of 12 are present in a given sample?
To find the number of moles in a sample, divide the sample's mass by the substance's atomic mass unit (amu). For a substance with an amu of 12, the number of moles in the sample can be calculated by dividing the sample's mass by 12.
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 molar mass of the substance in amu g mol?
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).
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.
