Results for Calculate The Amount In Moles Of Molecules For Each Substance. A) A Sample Of Ammonia NH3(g) Containing 8.1x1020 Atoms Of Hydrogen?
NH3 Molecules = ( 8.1 x 10^20 H atoms ) ( 1 NH3 molecule / 3 H atoms )
NH3 Molecules = 2.7 x 10^20 NH3 molecules
NH3 moles = ( NH3 molecules ) / ( N Avogadro )
NH3 moles = ( 2.7 x 10^20 NH3 molecules ) / ( 6.022 x 10^23 molecules / mole )
NH3 moles = 4.48 x 10^-4 NH3 moles <--------------
To calculate the amount in moles of NH3 molecules, first determine the number of moles of hydrogen atoms. Given that there are 8.1x10^20 atoms of hydrogen, divide this by Avogadro's number (6.022x10^23) to find the amount in moles. Since there are 3 hydrogen atoms in each ammonia molecule, the amount of NH3 molecules would be one-third of the amount of hydrogen atoms in moles.

Is hydrogen gas a pure substance?
Yes, hydrogen gas is a pure substance because it consists of only hydrogen atoms. It is a homogeneous mixture of identical molecules, making it a pure substance.
Is hydrogen gas a mixture?
No. Hydrogen is an element, which forms the molecule H2. Elements and homogeneous molecules (molecules that are all of one kind) are not considered mixtures; mixtures are by definition heterogeneous. An example is air, which is a mixture of nitrogen, oxygen, carbon dioxide, ozone, water vapor, and dozens of other elements and compounds.
A substance or a molecule containing carbon-carbon bonds or carbon-hydrogen bonds?
An organic compound is a substance or molecule containing carbon-carbon bonds or carbon-hydrogen bonds. These compounds are essential for life and are the building blocks of living organisms. Examples include carbohydrates, lipids, proteins, and nucleic acids.
Is hydrogen an example of a mixture?
No, hydrogen is not an example of a mixture. It is a pure element that exists as individual hydrogen molecules.
Is a hydrogen gas an example of a mixture?
Hydrogen gas is not an example of a mixture as it consists of only hydrogen molecules. It is a pure substance.
Has molecules only containing carbon and hydrogen?
Some molecules only contain Carbon and Hydrogen. They are called Hydrocarbons.
What is the structures of hydrogen?
In its elemental form hydrogen consists of diatomic molecules, each containing two hydrogen atoms.
What is carbonhydrate made of?
Molecules containing carbon, hydrogen and oxygen atoms

Is water the same thing as Saliva?
No, water and saliva are not the same. Water is a neutral substance composed of oxygen and hydrogen molecules, while saliva is a watery fluid produced in the mouth containing enzymes for digestion.
What molecules can form hydrogen with others like it?
NH3
What is the most likely source of a substance containing carbon hydrogen oxygen and nitrogen?
human cell.
