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.


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


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?

12.0 + (4.00000... X 1.0) = 16.0, to the justified number of significant digits.


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.


How many C atoms of mass 12.00 amu are in 12.00g of carbon?

I am not sure seeing as I am trying to answer that verry question at the moment. However, I believe that it would be 0% because the atomic mass you see on the periodic table is accualy an avrige of cabon 12 amu and all of its isotopes. thus the likleyhood that there is accualy a carbon particle with 12.011 is unlikely. course don't quote me on that im not entierly sure.

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?

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.
