What else can I help you with?
How it can prove that 1 amu is equal to 1.66067x10-27?
From Wikipedia: "... It is defined as one twelfth of the mass of an unbound neutral atom of carbon-12 ..." Thus, to prove that it has a certain mass, you would have to carry out exact measurements of the mass of carbon-12 atoms.
What is the difference between atomic mass and relative atomic mass?
Atomic mass is the measure of a mass of one atom in relation to 1/12 mass of Carbon 12 atom and measured in atomic mass unit(amu) or Dalton unit or grams/mol.Relative atomic mass is also the relative mass but does not have a unit but a ratio number.
An atomic mass unit is equal to?
One-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
How do you measure one second?
With a stop watch or a clock. If you're asking how do we determine what a second is (In the SI- International system of units), then that is determined by the oscillation of a Cesium Atom's Microwave. No matter what the conditions, the cesium atom's full oscillation will always equal one second. No matter where in the world. Really neat phenomenon.
Does one eighth equal 0.25?
No - one eighth is equal to 0.125. 0.25 is equal to one quarter.
Does the mass of one helium-4 atom equal one atomic mass unit?
The mass of a helium-4 atom is 4,002 602 amu.
What is the number of sulfur atoms that equal a mass of 32.07 amu?
One sulfur atom has an atomic mass of 32.07 amu. Therefore, to find the number of sulfur atoms that equal a mass of 32.07 amu, you would need just one sulfur atom.
What number of magnesium atoms equal 24.31 amu?
1: 24.31 is the approximate atomic weight of magnesium.
Is helium represented by he?
one mole of He
What is the atomic mass of an atom if its mass is approximately one third that of carbon 12?
The atomic mass number of an atom, if the atom's mass number is approximately equal to 0.33 that of carbon-12, would be 4. If the question is about actual masses rather than mass numbers, the mass of a helium-4 atom is about 4.00260 atomic mass units, while the mass of a carbon-12 atom is, by definition, exactly 12.000..... atomic mass units.
How many energy give 1 hydrogen atom when it fused?
If it is being fused it must be fused with something. If 2 atoms of hydrogen (deuterium) fuse to form one atom of helium then there is a difference of mass of (2.0141 x 2) amu - 4.002602 amu = 0.025598 amu 0.025598 amu x ( 931 Mev / amu) = 23.831738 Mev So if you want an amount per atom of hydrogen, divide by 2. 11.92 Mev per deuterium atom
Is 1 helium atom an atom?
Yes, 1 helium atom is an atom. Helium is an element, and each helium atom consists of a nucleus with 2 protons and 2 neutrons, surrounded by 2 electrons.
How many kinds of atoms does helium have?
Helium has one kind of atom: helium.
How is the atomic mass unit defined?
a unit of mass used to express atomic and molecular weights, equal to one-twelfth of the mass of an atom of carbon-12. It is equal to approximately 1.66 x 10^-27 kg.
What is one twelfth of carbon atom?
One atomic mass unit (amu)
What does amu mean in the atomic mass of an element aside of it?
AMU stands for atomic mass unit. It is a unit of mass used to express atomic and molecular weights. One atomic mass unit is defined as a mass equal to one twelfth the mass of a carbon-12 atom.
What is the mass of six helium atoms?
32 g
