I am not completely sure what your question is, but I think you are asking about the molar mass? It is a mole conversion. For example, if you start with atoms and want grams, you would need to get rid of the atoms unit first then get rid of the mols unit: so you would have to multiply it by (1 mol / Avogadro's number) X (molar mass / 1 mol) = this is the conversion factor that gives you grams. I hope this helped!

Answer:

The answer is molar mass.

Explanation:

Molar mass is defined as the mass of substance (in grams) that occurs in one mole of that substance.

Molar Mass = M = mass in gram of substance/n. of moles of substance

Answer:

$Hope this helps you$ A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus. $Enjoy your day$

(b) The mass of a single molybdenum atom is 1.59×10-22 g. Suppose enough Mo atoms were lined up like beads on a string to span a

serious [3.7K]

Answer:N=1151724138 atoms

Explanation:The atomic radius of molybdenum atom is 145 picometers so lining up molybdenum atoms is like lining up the beads of radius 145 picometers

so one bead would cover the length of 145*2=290 picometers

hence the atom's diameter =D=290 picometers

D=290 *10^(-12)

$D=290/1000000000000$
