How many times an atom of calcium is heavier than an atom of oxygen?
Average atomic mass of Ca = 40.1 Average atomic mass of O = 16.0 Mr(Ca)/Mr(O) = 40.1/16.0 = 2.51 Thus the calcium atom is about 2.5 times heavier than the oxygen atom.
What is the mass of helium?
helium = 4 molar mass
What are the subatomic particles of calcium?
Calcium has 20 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a calcium atom = Mass number - 20
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
40, the sum of the protons and neutrons.
What element has a mass number of 56 with 36 neutrons?
A mass number is the sum of numbers of protons and neutrons in an atom. Therefore, an element with a mass number of 65 and 36 neutrons contains (65 - 36) or 29 protons and is therefore an atom of copper.
What is the mass of a calcium atom compared with the mass of a helium atom?
5
How many times greater is the mass of bromine atom compared to a helium atom?
18.96 times greater = 19.96 times as great.
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.
How many times lighter is a helium atom than carbon?
A helium-4 atom is just about 1/3 the mass of a carbon-12 atom.
What is the mass of a helium atom?
4.0026 amu
What is the mass of a single atom of helium?
The atomic mass of Helium is 4.002602. The atomic mass is the combined number of protons and neutrons in the atom.
What is heavier nitrogen or helium?
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
What has a greater number of atoms a gram of lead or a gram of uranium?
The lead atom is way heavier than the helium atom. We know this by referring to the Periodic Table of Elements. The atomic mass of lead (Pb) is 207, while that of helium (He) is 4. Therefore, we can estimate that an atom of lead is about 50 times heavier than an atom of helium.
What is the mass number of helium atom?
The atomic number of helium is 2. Its mass is 4.002602 u ± 0.000002 u
The mass of an atom compared to the mass of a carbon-12 atom is called the?
Isotope.
What is the atomic mass for an atom of helium?
4.0026 amu
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
