∙ 14y ago
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.

What is the percent composition of ammonium carbonate?
Can you be more specific? Percent composition is usually the percent of an element in a compound.
What is the percent composition of aluminum cyanide?
Percent composition is a calculation of how much of the molecular weight of a compound is due to a particular element within that compound. For Al(CN)3, the percent composition of aluminum would be 27 / (27 +[12 x 3] + [14 x 3]) = 25.7%
What is acetone's percent composition by mass?
%C= 62.0% %H2= 10.4% %O2= 27.5% To find these, you divide the molar mass of the specific element in the compound divided by the molar mass of the entire compound.
Why is bronze a compound?
Because no chemical reaction takes place between zinc and copper which constitute it.
How do you know when to solve for a empirical formula?
If it tells you to find the empirical formula when percent composition is given or if the mass of each element is given in a specific compound.
Does The element with the largest subscript in a formula have the largest percent by mass in the compound?
Sometimes, but not necessarily: The largest percent by mass in a compound is that of the element for which the product of the subscript and the atomic weight is highest. For example, there is more carbon than hydrogen by mass in CH4.
What is the percent compistion of a compound?
The percent composition of a compound tells the amount of each element in the compound as a percentage. It is possible to find if the mass of an element and the total mass of the compound is known.
How do you calculate the grams of an element in a specific amount of a compound?
