A silver sample contains 52 atoms each having 60 neutrons and 48 atoms each having 62 neutrons What is the sample's average atomic mass?

The total mass of all the silver atoms would be 10,770,
65(47+60) + 35(47+62) = 10,770 The total number of silver atoms is 100, 65 + 35 = 100 Dividing the total mass by the number of atoms gives us a 10770/100 = 107.7 for an Atomic Mass by these numbers.

∙ 15y agoIts just an average.
(52x50+48x62)/100 = (2600+2976)/100 = 55.76

What does the atomic nucleus contains?
The atomic nucleus contains protons (at least one) and zero or more neutrons.
Is it true The number of neutrons in an atom is referred to as the atomic number of that element?
No, the atomic number refers to the protons of an atom, and for the most part the electrons. The atomic mass refers to the neutrons of an element in a way; the atomic mass consists of protons and neutrons, so if you subtract the amount of protons from the atomic mass, you get the amount of neutrons. For example oxygen has an average atomic mass of 16.01 and has 8 protons, so 16.01 atomic mass-8 protons=8.01 average neutrons. Now this is just for the average amount of neutrons, which is changed by isotopes (atoms with different amounts of neutrons).
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
What describes the bohr atomic model?
The nucleus contains protons and neutrons and is orbited by electrons. ( Apex 2021)
What is the average atomic mass compared to atomic mass?
Atomic mass is the number of protons and neutrons in an atom.

Is the atomic weight the same as the atomic number?
No, the atomic number is the number of protons that an atom contains. Atomic weight is the number of protons and neutrons.
What is the average atomic mass compared to the atomic mass?
Atomic Mass is the number of protons and neutrons in an atom.
If Phosphorous has an atomic mass of 30 and atomic number of 15 how many neutrons does it have?
Atomic mass is equal to the number of protons + neutrons present in the nuclide. The atomic number is defined as the number of protons in the nuclide. Therefore to find the number of neutrons use the formula: atomic mass = #protons + # neutrons solving for # of neutrons you get: # neutrons = atomic mass - # protons plug in the given values: #neutrons = 31 - 15 # neutrons = 16

What is the dense particle in the center of the atom which contains protons and neutrons?
This is the atomic nucleus.
What is the dense particle in the center of an atom which contains protons and neutrons?
This is the atomic nucleus.
If the atomic mass of an atom is 38 and the atom contains 15 protons how many neutrons does the atom contain?
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
What is the average number of neutrons in carbon?
6 neutrons. you take the mass, and subtract the atomic number.
What is the average atomic mass compared to atomic mass?
Atomic mass is the number of protons and neutrons in an atom.
