What element has an atomic mass of 55.85?
Manganese is a metal element. Mass number of it is 55.
How many neutrons are in an atom of cesium 137?
In atomic form (as opposed to being an ion), cesium-137 has 55 electrons, just as all cesium atoms have.
What element has the atomic mass of 56?
The element with an atomic number of 51 is Sb - Antimony; atomic weight = 121.75.
What is the percent composition of Cs3N?
The gram atomic mass of cesium is 132.905 and that of nitrogen is 14.0067. The formula of the compound shows that there are three atoms of cesium for each atom of nitrogen. Therefore, the percent of cesium in the compound is: 100{3(132.905)/[3(132.905) + 14.0067]} or 96.6063 % cesium, to the justified number of significant digits. By difference the per cent nitrogen is 3.3937.

What is the mass of 5 moles of cesium?
One atom of cesium has a mass of 132.9054 amu, and one mole of cesium has a mass of 132.9054 grams, so five moles of cesium has a mass of 664.527 grams.Multiplying the mass of a particle (which can be an atom, molecule, etc.) by Avogadro's number (6.022x1023, the number of particles of a substance in 1 mole) will give you the mass of a mole of that particle, or molar mass, in grams. Avogadro's number is special because the molar mass of a substance will be the same number as its atomic mass, only in grams!
