Very nearly all of the mass of an atom is found in the nucleus in the form of Protons and Neutrons. Electrons and "binding energy" contribute a tiny amount of additional mass.

What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

What is the mass of 4.9810e21 platinum atoms?
The mass of 4.9810e21 platinum atoms is 0,000 042 g.
Is Density is the measurement of the number of atoms or molecules in a given volume?
Density is the relationship between mass and volume. the number of molecules in a given mass is molarity. -------------------------------------------------- No it is not. Because atoms come with different masses, so you could have 1 billion atoms of hydrogen occupying the same volume as 1 billion atoms of gold but the gold would weigh more than the hydrogen.
Does mole of carbon atoms have a different mass than a mole of sulphur atoms?
Yes. To find out the mass of a mole of atoms of any given element, see the atomic mass given on the periodic table. A mole of carbon atoms has a mass of 12.011 grams. A mole of sulfur atoms has a mass of 32.06 grams.
The mass of a sample of nickelaverage atomic mass 58.69 amu is 11.74g how many atoms does it contain?
the number of atoms is equal to the mass of the sample divided by its molar mass times one mole 11.74g / 58.69g/mol * 6.02*1023 atoms/mol = 1.2*1023 atoms approximately
What does most of the atoms mass come from?
the nucleus
Do all protons have the same mass if they come out of helium?
All protons have the same mass regardless of where they come from. It should be noted, however, that most of the mass in atoms comes from the forces holding the atom together.
What can come from splitting the nuclei of atoms?
More nuclei of more atoms than you started out with, less mass than you started with, and some energy.
How many Helium-atoms and Carbon-atoms do you have if you have He-atoms with mass of 40amu and C-atoms with mass of 120amu?
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms

Is fusion nuclear decay or nuclear synthesis?
Fusion is nuclear synthesis, combining atoms of lesser mass into atoms of greater mass. Decay is reducing the mass of larger (unstable) atoms to form atoms of lesser mass.
How does density relate to atoms found in an object?
Density is defined by the equation d = m/v, or mass / volume. So yes, they are related, and if one has the volume of an atom and the atomic mass, they can figure out the density. Keep in mind that the vast majority of the mass in an atom is in the nucleus, but the majority of the volume is given by the electron cloud (which has negligible mass.)
What is true of an atoms nucleus?
It contains Protons and Neutron's.
What does adding s neutron to an atoms nucleus do to the atoms mass?
Increases it by one mass unit.
What is the mass in grams of 2x1012 atoms of potassium?
What is the mass, in grams, of 2 × 1012 atoms of potassium?
What is the mass of 4.9810e21 platinum atoms?
The mass of 4.9810e21 platinum atoms is 0,000 042 g.
What has more mass 100 hydrogen atoms 4 sulfur atoms or 1 lanthanum atom?
100 Hydrogen atoms have an atomic mass of 100.794, 4 Sulfur atoms have an atomic mass of 128.26, and 1 Lanthanum atom has an atomic mass of 138.90547.
