What is the mass of 1 mol of rubidium?
According to the periodic table, the atomic mass of rubidium, Rb is 85.5. This is numerically equal to the molar mass in g/mol. Therefore the mass of 1 mol of Rb is 85.5g.Mass of 1 mol means the molar mass of the element. Molar mass of Rubidium is 85.47 gmol-1. Rb is in the 1st group.
What is atomic mass of an atom equal to?
The atomic mass of an element is equal to the number of protons.
Is it true that The atomic mass is equal to the atomic number?
No, the atomic mass number is the number of protons plus the number of neutrons. The atomic mass of an atom is the total mass in a motionless atom.
Are the number of neutrons equal to the atomic number minus the atomic mass?
false
What is the unified atomic mass unit equal to?
Aunified atomic mass unit is equal to one-twelth the mass of a carbon-12 atom.
What is carbons structure?
it has 6 electons. atomic number is 6. Atomic Mass is 12.011

What is atomic mass of an atom equal to?
The atomic mass of an element is equal to the number of protons.
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
How many neutrons dose 12 mass number of carbons has if the atomic number is 6?
6
Atomic mass is equal to what?
atomic mass unit is equal to one-twelfth of the mass of a carbon-12 atomic mass is equal to one-twelfth of the mass of a carbon-12Atomic Mass is equal to the number of protons and neutrons.
The atomic mass of an atom is equal to the sum of numbers of what?
protons + electrons= atomic mass NUMBER, not the atomic mass.
Is atomic mass unit a SI unit of an atomic mass?
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
What does the atomic mass equal?
mass of neutrons + mass of protons
What do protons and neutrons equal?
It may or may not equal, neutrons are responsible for stability of nucleus.
What atomic mass is equal to the atom on the periodic table?
number of protons = atomic mass
Why doest the atomic number equal the atomic mass?
atomic mass is contributed mainly by protons and neutrons. it is the mass of an atom. atomic number on the other hand is contributed by protons and is equal to the number of protons in the atom
