AMU stands for Atomic Mass units; the number of units an element has is called its atomic mass. The atomic mass of carbon is exactly 12, by definition.
44.010 g/mol You can sum up atomic weight of 1 carbon and 2 oxygen to this figure.
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.

From the formula of the compound, each molecular unit contains 2 copper atoms, 4 oxygen atoms, one carbon atom, and 2 hydrogen atoms. Multiplying each of these by its corresponding atomic mass gives 127 atomic mass units ("amu") of copper, 64 amu of oxygen, 12 amu of carbon, and 2 amu of hydrogen. Copper is clearly present in the largest percent by mass.
To calculate the number of moles of carbon dioxide in 19 grams, divide the given mass by the molar mass of carbon dioxide, which is approximately 44 grams/mol. Therefore, 19 grams of carbon dioxide is equal to 19/44 ≈ 0.43 moles.
Ethylene- C2H4 Find the atomic masses for each element and multiply it by the number of atoms in the compound, then add. C- 12.0 * 2= 24.0 H- 1.00 * 4= 4.00 ----------------------- 28.0 Take the masses for each element and divide it by the total mass. Then change the answer to get the percent. C 24.0 / 28.0= .857 = 85.7% H 4.00 / 28.0= .143 = 14.3% Ethylene is 85.7% Carbon and 14.3% Hydrogen
The atomic mass unit (amu) of a carbon dioxide (CO2) molecule is approximately 44 amu. This is calculated by adding up the atomic masses of one carbon atom (12 amu) and two oxygen atoms (16 amu each) in the molecule.

The mass of carbon in carbon dioxide is 12 grams per mole.
Mass of Carbon-12 = 12 amu 5times of mass of Carbon-12 atom = 5 x 12 = 60 amu So atomic mass of element X = 60 amu Rachel- www.examville.com ,tutor
The atomic mass unit (amu) is based on the carbon-12 isotope, with 1 amu defined as one twelfth of the mass of a carbon-12 atom. This definition allows for easier comparison of the masses of different atoms.
how many moles of CF4 are there in 171 g of CF 4
The mass of one molecule of carbon monoxide, CO, is approximately 28 atomic mass units (amu). This is calculated by adding the atomic masses of one carbon atom (12 amu) and one oxygen atom (16 amu) together.
A chlorine atom is more massive than a carbon atom. Chlorine has an atomic mass of 35.45 amu, while carbon has an atomic mass of 12.01 amu.
