That is 1 mole of Bi and that would be 6.022 X 10^23 atoms of Bi, so one atom of Bi would be 1/6.022 X 10^23
= 1.66 X 10^-24 * 208.9804 grams
= 3.47 X 10^-22 grams

How do you calculate a mole of an atoms weight in grams?
you take the atomic mass of the atom (or molecule) and you have the mass in grams
What is the number of protons in an atom known as?
It is called the atomic no. of element. It is also equal to the no. of electrons in the atom.
What is the atomic number of nitrogen (N)?
The atomic number of nitrogen (N) is 7. The atomic weight of N is 14.00674 grams per mole. Nitrogen gas exists as a diatomic molecule: N2.
What is a atomic number in a element?
The atomic number of an element refers to the number of protons in the nucleus of the atom of that element, and is unique to each element. The atomic weight is the weight of an atom of the element compared with the weight of a single proton, and consists of number of protons and neutrons in the nucleus of the atom of that element, and different atoms of the same element can have different numbers of neutrons, and therefore more than one atomic weight: it is usually given as an average. the atomic number on an element is simply the number of protons and electrons in the element. however, it is not the total number of them.
What happens to an atom in terms of atomic mass and weight when it loses one particle?
If an atom looses an electron, neither the atomic mass nor atomic weight change appreciatively. If it looses a proton or neutron, both atomic mass and atomic weight decrease by one and it becomes an atom of a different element (on loss of a proton), or a different isotope of the same element (upon loss of a neutron).
How do you calculate a mole of an atoms weight in grams?
you take the atomic mass of the atom (or molecule) and you have the mass in grams
One mole of boron has a mass of how many grams?
10.81g This is found by looking at the atomic weight. The atomic weight refers to the mass of a singe atom in units of AMU (atomic mass units) and it also refers to the mass of one mole of the element in grams.
What do you mean by 1 atom of Carbon and 1 gram atom of Carbon?
One atom of carbon is one atom of carbon. One gram atom of carbon is the atomic weight (14 in the case of carbon) in grams, so it would be 14 grams of carbon.
Is the atomic mass different than atomic weight?
Not to a chemist, when they are both expressed in grams! For a physicist, "mass" is the preferred term because it is an inherent property of the material, whereas the weight will vary if an atom is in a different gravitational field than that of the Earth. In physics, "weight" is not expressed in simple "grams" but rather in "grams force".
What is the atomic weight of phosphorus?
The atomic number of phosphorus (P) is 15.The atomic weight of P is 30.973762 grams per mole.See the Web Links to below this answer for a periodic table with more information about this element!
What is the atomic weight of Helium atom?
Helium atom has 2 protons and 2 neutrons (that accounts for its atomic weight). The atomic weight of helium is 4.00260
How can you figure out the number of neutrons in an atom?
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.

Which is greater the mass of a carbon atom or a chlorine atom?
Florine has a greater Atomic Weight because Carbon has a Atomic Weight of 12 amu (atomic mass units) while Florine has a Atomic Weight of 19.
Is a lead atom heavier than a helium atom?
Yes; helium has an atomic weight of 4.00260, and lead has an atomic weight of 207.2.
Term for an atom that has the same atomic number as another atom but differs in atomic weight?
This is the definition of an "isotope".
A given atom of calcium has an atomic number of 20 and an atomic weight of 42 This atom has?
22 neutrons.
