∙ 16y agoAg-107 and Ag-109 are the two common isotopes of silver. There are nearly a dozen known isotopes of silver, but all are radioactive and decay quickly (in half-life lengths from 24.6 seconds to 41.3 days) into something else, except for the two stable isotopes, 107 and 109. Chemically, all isotopes of silver behave the same, and all are indeed silver. It is only their atomic masses that are different. Ag-107 has 47 electrons, and its nucleus contains 47 protons and 60 neutrons, for an Atomic Mass of 106.9. Ag-109 has 47 electrons, and its nucleus contains 47 protons and 62 neutrons, for an atomic mass of 108.9. Natural silver consists of about 51.8% Ag-107 and about 48.2% Ag-109, for an average atomic mass of about 107.9. Any silver you are likely to have - jewelry, bullion, coins, or whatever - consists of these ratios of these isotopes. http://www.webelements.com/webelements/scholar/elements/silver/nuclear.html
The mass of Ag-109 can be calculated by adding 2 to the mass number of Ag-107 since Ag-109 has 2 more neutrons. So, the mass of Ag-109 would be 108.905.

What is the formula for mass percent?
mass % of element X = mass of element X ____________________ X 100 total mass of compound or mass of solute _____________________________ X 100 mass of solute + mass of solvent
What equation shows conversation of mass?
The equation that shows conservation of mass is the mass of reactants equals the mass of products in a chemical reaction. This can be represented as: Mass of reactants = Mass of products.
What is the equation for the conservation on mass?
The equation for conservation of mass is mass in = mass out. This means that the total mass of a system remains constant over time, with the amount of mass entering a system equaling the amount of mass leaving the system.
What is the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
In a balanced chemical reaction the total mass of the products always equals the total what?
In a balanced chemical reaction the total mass of the products always equals the total mass of reactants; this is the law of mass conservation.
How many electrons does Ag109 have?
178456
What is the amount of matter in an object?
Its mass.
How is mass different from mass?
Mass and mass are the same thing.
How do you find a mass by difference?
Mass of the contained material = Total mass (mass of the container + mass of the material) - Mass of container
Does mass have mass?
Yes, mass has mass. It is, therefore, matter. If mass did not have mass, then it is "something" with no mass. That would make it "non-matter" and perhaps it might be energy.
What properties stay the same during physical and chemical change?
mass mass
How about air and mass.do they have mass?
Air has mass. Mass is a property and does not have mass
What is the mass of an atom found by?
The mass of an atom is primarily determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass since electrons have negligible mass. The exact mass of an atom can be found by adding up the masses of its protons, neutrons, and electrons.
What determines an element's mass?
the mass of protons + the mass of neutrons = mass of the element
How do you solve for percent by mass?
reg.% by mass mass% m/m mass of solute mass of solution=x100
What are the three other names for Midnight Mass Dawn Mass and Christmas Day Mass?
Angel's Mass, Shepherd's Mass, and Mass of the Divine Word.
Mass by difference?
Mass by difference is a method used in analytical chemistry to determine the mass of a component in a mixture by weighing the entire mixture before and after the component of interest is removed. The mass of the component is then calculated as the difference between the two measurements. This technique is commonly used when the component of interest cannot be easily separated or directly measured.
