What is the mass number of a carbon atom with 5 neutrons?
Carbon's atomic number is 6, therefore it has 6 protons in its atoms. Mass number is the sum of protons and neutrons in the nucleus, which is 6 + 5 = 11.
What do you mean by 1 atom carbon and 1 gram of carbon?
one gram of carbon* Avogdo's number =number of atom (many atom) one atom of carbon mean carbon have a 6 electron and 12 molar mass
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.
An atom of hydrogen and an atom of carbon are?
An atom of hydrogen has one proton and one electron, with a mass of approximately 1 atomic mass unit. An atom of carbon has 6 protons, 6 neutrons, and 6 electrons, with a mass of approximately 12 atomic mass units.
The mass of a hydrogen atom is 1.0 amu and the mass of a carbon atom is 12.0 amu What is the molar mass of methane CH4?
To find the molar mass of methane (CH4), sum up the atomic masses of all the atoms in the molecule: (1 hydrogen atom x 4) + (1 carbon atom) = 4 g/mol (hydrogen) + 12 g/mol (carbon) = 16 g/mol. Therefore, the molar mass of methane (CH4) is 16 g/mol.
One-twelfth the mass of a carbon-12 atom is used to define?
Atomic mass.
Why atomic mass of an atom is define as relative atomic mass?
It is calculated as the ratio of the mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. In fact, the weighted average of the mass of an atom of an element - weighted according to its isotopic abundance.
What is one twelfth of carbon atom?
One atomic mass unit (amu)
Atomic mass unit is equal to what?
Unified atomic mass unit, a small unit of mass used to express atomic and molecular masses. The atomic mass unit is equal to one-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
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 relationship between atomic mass and average atomic mass?
The average atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. It is, the mass of an atom of the substance, rescaled so that carbon-12 would have a mass of 12.
An atomic mass unit is equal to?
One-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
Why is atomic mass of an atom is defined as relative atomic mass?
It is calculated as the ratio of the mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. In fact, the weighted average of the mass of an atom of an element - weighted according to its isotopic abundance.
Why atomic mass of atom is defined as relative atomic mass?
It is calculated as the ratio of the mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. In fact, the weighted average of the mass of an atom of an element - weighted according to its isotopic abundance.
Why atomic mass of an atom is defined as relative atomic mass?
It is calculated as the ratio of the mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. In fact, the weighted average of the mass of an atom of an element - weighted according to its isotopic abundance.
Has a mass of one atomic mass you?
One-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
What is the standard on which the amu is made?
The atomic mass unit uses carbon-12 as a standard. The atomic mass unit is one twelfth of the mass of one atom of the isotope carbon-12.
