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.
What else can I help you with?
What is the mass of a carbon dioxide molecule?
44.010 g/mol You can sum up atomic weight of 1 carbon and 2 oxygen to this figure.
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.

In the compound Cu2OH2CO3 which element is present with the largest percent by mass?
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.
How many moles of carbon dioxide are there in 19 grams of carbon dioxide?
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.
What is the percentage of composition of hydrogen in C3H4?
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
What is the amu of a carbon dioxide molecule?
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.
What is the mass of carbon dioxide?
44.0095 amu
What is the mass of carbon-dioxide?
44.0095 amu
What is the atomic mass unit for carbon dioxide?
44 amu
What is the atomic weight of carbon dioxide?
44.0095 amu
What is carbon dioxides atomic weight?
44.0095 amu
What is the mass of carbon in carbon dioxide?
The mass of carbon in carbon dioxide is 12 grams per mole.
Atom of element X has mass 5 times than that of Carbon-12 What is its atomic mass?
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
What element is the atomic base unit amu based off of?
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.
What is the mass of 7.801018 carbon atoms?
how many moles of CF4 are there in 171 g of CF 4
What is the mass of one molecule of carbon monoxide?
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.
Which is more massive a chlorine atom or a carbon atom?
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.
