Helium has Atomic Mass 4.003 a.m.u.
What else can I help you with?
How many times lighter is a helium atom than carbon?
A helium atom is four times lighter than a carbon atom. This is because helium has two protons and two neutrons in its nucleus, while carbon has six protons and six neutrons. The atomic mass of helium is approximately 4 atomic mass units, while the atomic mass of carbon is approximately 12 atomic mass units.
How many times greater is the mass of bromine atom compared to a helium atom?
18.96 times greater = 19.96 times as great.
What is the mass number of carbon atom?
The mass number of a carbon atom is 12. This number represents the total number of protons and neutrons in the nucleus of the carbon atom.
The relative atomic mass of an atom can be found by comparing the mass of the atom to the mass of?
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
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.
What is heavier one atom carbon or one atom gold?
The Atomic Mass of Carbon is 12.0107 The atomic mass of Gold is 196.96657 So an atom of Gold is about 16 times heavier than an atom of Carbon.
How many times an atom of sulphur is heavier than an atom of carbon?
An atom of sulfur is about 2.5 times heavier than an atom of carbon. This is because sulfur has a greater atomic mass (32) compared to carbon (12).
How many times lighter is a helium atom than carbon?
A helium atom is four times lighter than a carbon atom. This is because helium has two protons and two neutrons in its nucleus, while carbon has six protons and six neutrons. The atomic mass of helium is approximately 4 atomic mass units, while the atomic mass of carbon is approximately 12 atomic mass units.
How many times heavier is one atom of carbon than one atom of oxygen?
It isn't. Carbon is 6th on the Periodic Table and Oxygen is 8. Oxygen is the heavier element. mass of oxygen / mass of carbon 15.99g / 12.01g = 1.33 heavier than carbon
What is the mass of a carbon atom?
The mass of a carbon atom is approximately 12 atomic mass units.
How many times an atom of carbon is heavier than atom of carbon?
You need to restate your question as you have asked the difference between something and itself.
How many times an atom of sulfur is heavier than an atom of carbon?
Sulphur has a molar mass of 32.065. Carbon has a molar mass of 12.01. 32.065 / 12.01 = 2.67. So an sulphur atom is 2.67 heavier than an carbon atom.
How many times greater is the mass of bromine atom compared to a helium atom?
18.96 times greater = 19.96 times as great.
What is the mass number of carbon atom?
The mass number of a carbon atom is 12. This number represents the total number of protons and neutrons in the nucleus of the carbon atom.
The mass of an atom compared to the mass of a carbon-12 atom is called the?
Isotope.
The relative atomic mass of an atom can be found by comparing the mass of the atom to the mass of?
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
Element A has atom which is 3 times lighter than that of Carbon-12 Calculate its atomic mass?
Mass of C-12 atom = 12 amu mass of C-12 atom = am So atomic mass of A = 4 amu source ; www.examville.com
