If you mean "how does one determine an atoms Atomic Mass?", then the answer would be to find a Periodic Table of elements where the whole numbers indicate atomic number and the other indicating atomic mass. Atomic number is generally described as the number of protons in a naturally occurring atom of a given element, and the atomic mass is the number of protons + number of neutrons in an atom.

Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
What is the unit of weight for elements?
The unit of weight for elements is typically measured in atomic mass units (amu) or grams. The atomic mass unit is defined as one twelfth of the mass of a carbon-12 atom.
What is the relative atomic mass of phosphoric acid?
The relative atomic mass of phosphoric acid (H3PO4) is calculated by adding the atomic masses of all the constituent atoms. Phosphoric acid contains one phosphorus atom with an atomic mass of approximately 31.0, three hydrogen atoms with an atomic mass of approximately 1.0 each, and four oxygen atoms with an atomic mass of approximately 16.0 each. Adding these together gives an approximate relative atomic mass of 98.0.
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 relationship between the atomic mass of an element and 1 mole of that elements atoms?
The atomic mass is grams/mole So when you have e.g. 12 grams of carbon which has atomic mass = 12, you have one mole. ( Avogadro's number is one mole: 6.02×10²³ )
How can one determine the molar mass of a solute?
To determine the molar mass of a solute, you can add up the atomic masses of all the atoms in the chemical formula of the solute. This can be found on the periodic table.
If the atomic weight of nitrogen is 14.01 what is the mass of the nitrogen atoms in one mole of cadmium nitrate Cd(NO3)2?
To calculate the mass of nitrogen atoms in one mole of cadmium nitrate, we first need to determine the molar mass of Cd(NO3)2. The molar mass would be the sum of the atomic weights of Cd, N, and 6 O atoms in the formula. After adding these atomic weights, we can find the mass of nitrogen atoms in one mole of cadmium nitrate by multiplying the molar mass by the ratio of nitrogen atoms in the formula.
How can one determine the mass of an element in a compound?
To determine the mass of an element in a compound, you can use the chemical formula of the compound and the atomic mass of the element. Multiply the atomic mass of the element by the number of atoms of that element in the compound, then add up the masses of all the elements present in the compound to find the total mass.
Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
What is the mass of atoms of sulfur?
The Atomic Mass of one (1) atom of sulfur is 37.02. The atomic mass of three (3) atoms of sulfur is 96.21. 32.07 * 3 = 96.21
What is the difference in molar mass and atomic mass?
molar mass is the actual mass of the one atom but relative mass is the average isotopes of the atoms.------------------------------------------Atomic mass is the mass of an isotope, expressed in atomic mass units.Molar mass is the mass of molecule, calculated from the atomic weights of the contained chemical atoms, expressed in grams.
What is the significance of "da" in chemistry and how does it relate to the measurement of atomic mass?
In chemistry, "da" stands for Dalton, a unit used to measure atomic mass. It represents the mass of one atomic particle, which is approximately equal to the mass of a proton or neutron. The atomic mass of an element is measured in Daltons, which helps scientists determine the relative mass of different atoms and molecules.
What is the relationship between the atomic mass of an element and a mole of that elements atoms?
The mole is the atomic weight expressed in grams.
How can one determine the molar mass of an empirical formula?
To determine the molar mass of an empirical formula, you need to calculate the sum of the atomic masses of all the elements in the formula. This can be done by multiplying the atomic mass of each element by the number of atoms of that element in the formula, and then adding up all the results.
What is the unit of weight for elements?
The unit of weight for elements is typically measured in atomic mass units (amu) or grams. The atomic mass unit is defined as one twelfth of the mass of a carbon-12 atom.
How can one determine the theoretical mass of a substance?
To determine the theoretical mass of a substance, one must calculate the molecular weight of the substance by adding up the atomic weights of all the atoms in its chemical formula. This can be done using the periodic table to find the atomic weights of each element present in the substance.
What is the mass of one mole hydrogen atoms?
Hydrogen has an atomic mass of 1.00794 or 1.
