Silver has the Atomic Mass weight of 107.87. Round to the nearest whole number. The mass number of silver is therefore
108
.
How do you find the atomic mass of silver?
- Average atomic mass
Ag
= (mass
Ag – 107
* abundance
Ag – 107
) + (mass
Ag – 109
* abundance
Ag – 109
) =(106.90509 * 0.5186) + (108.90470 * 0.4814) … - Look up the element on a periodic table to check your answer. The average atomic mass is usually written underneath the element symbol.
What is the atomic mass of silver rounded?
As you can see, silver has an atomic mass of
107.87 u
. To find the mass number of the most common isotope of silver, round this value to the nearest whole number. This means that the most common isotope of silver is silver-108.
What is the atomic mass of silver 107?
Silver has two naturally occurring isotopes. Ag-107 has an abundance of 51.82% and mass of
106.9 amu
. Ag-109 has a relative abundance of 48.18% and a mass of 108.9 amu.
How do we calculate atomic mass?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu).
By adding together the number of protons and neutrons and multiplying by 1 amu
, you can calculate the mass of the atom.
Which element has a mass number of 79?

Where is the atomic mass?
Experimental data showed that the vast majority of the mass of an atom is concentrated
in its nucleus
, which is composed of protons and neutrons. The mass number (represented by the letter A) is defined as the total number of protons and neutrons in an atom.
How do you find the mass?
Mass is always constant for a body. One way to calculate mass:
Mass = volume × density
. Weight is the measure of the gravitational force acting on a mass. The SI unit of mass is “kilogram”.
What is an average atomic mass?
The atomic mass of an element is
the average mass of the atoms of an element measured in
atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
Which element has a mass number of 10?
Neon
has an atomic number of 10 and a mass number of 20.1797.
