In 3 formula units of (NH4)2HAsO4, there are 6 nitrogen (N) atoms, 24 hydrogen (H) atoms, 3 arsenic (As) atoms, and 12 oxygen (O) atoms. Each formula unit contains 2 nitrogen atoms, 8 hydrogen atoms, 1 arsenic atom, and 4 oxygen atoms. Therefore, multiplying by 3 gives the total number of atoms for each element.
What else can I help you with?
How can the number of atoms of an individual element be determined by using a chemical formula?
The subscript number after the element symbol, such as the 2 in H2O, tells how many atoms in each molecule. In the example, the 2 refers to H (hydrogen). If there is no number present, then 1 is implied. So H2O has 2 hydrogen and 1 oxygen.
What does a chemical compound formula tell you?
It tells what elements are present in a molecule and how many atoms of each element are present.
What indicates all the elements in the compound as well as how many atoms of each element are present?
A molecular formula.
What formula represents the actual number of atoms of each element in a compound?
A formula that gives the ratio of elements in a compound is called an empirical formula. On the other hand, the formula that shows the number of atoms in each element present in a molecule is called a molecular formula.
How many atoms of element O are represented in the formula?
To determine the number of oxygen (O) atoms in a formula, you need to specify the compound or molecule in question. Once you provide the formula, I can help you calculate the number of oxygen atoms present.
What shows how many atoms of each element are in a unit of substance?
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
What does the subscript indicate in the chemical formula?
The number of atoms of that element in the molecule
What shows how many atoms of each element are in a unit of a substance?
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
The number of atoms of each element present in the molecule is indicated by what?
The number of atoms of each element present in a molecule is indicated by the subscript to the right of the element symbol in the chemical formula. For example, in H2O, there are 2 hydrogen atoms and 1 oxygen atom.
What three things does a chemical formula tell you?
The type and the number of atoms of each element present.
In a chemical formula what do subscripts mean?
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.
What is a symbol that shows the elements in a compound and the ratio of atoms?
You think probable to the chemical formula of a molecule.
How can the number of atoms of an individual element be determined by using a chemical formula?
The subscript number after the element symbol, such as the 2 in H2O, tells how many atoms in each molecule. In the example, the 2 refers to H (hydrogen). If there is no number present, then 1 is implied. So H2O has 2 hydrogen and 1 oxygen.
What does a chemical compound formula tell you?
It tells what elements are present in a molecule and how many atoms of each element are present.
What indicates all the elements in the compound as well as how many atoms of each element are present?
A molecular formula.
What does the subscript in a formula tell you?
The subscript in a formula typically indicates the number of atoms of an element present in a molecule. It is used to specify the ratio of atoms in a compound or the number of atoms in a polyatomic ion.
List the nameof each element that appears in the formula and give the number of atoms of each element present. HOOCC6H4OOCCH3?
Hydrogen - 8 Oxygen - 4 Carbon - 9 So, shorthand formula is C9H8O4 = aspirin
