Taking an example.
6H3PO4
This means that there are 6 molecules ( 6 molar ratios) of H3PO4
The '3' is the number of hydrogen (H) atoms in the molecule
The '4 ' is the number of oxygen (O) atoms in the molecule.
NB The '3' & '4' should acutally be written as subscript.
Another example
Mg(OH)2
The '2' outside the brackets indictates that there are '2' hydroxide (-OH) ions in the molecule.
Finally,
CH3 (CH2)14COOH
The '2' & '3' as indicated above. however, the ''14' indicates that there are '14' CH2 (ethylene) in the chain . It is written in this form in order not to write a long chain of 'CH2.

(NH4)2CO3
It means that there are 4 atoms of hydrogen in one molecule of ammonium, as all sub scripted numerals do in chemical formulas, the the 2 on the outside of the parentheses means multiply the outside subscript by the inside numbers to get full atom count. Remember, this is implied; N1.

How many carbon atoms in cobalt acetate?
The formula for cobalt acetate is Co(C2H3O2)2. According to the formula, there are four carbon atoms in each formula unit. When an ion is in parentheses, you multiply the subscripts inside the parentheses times the subscript outside the parentheses to find the total number of atoms of an element.
How many oxygen atoms are there in the formula for aluminum nitrate?
The formula for aluminum nitrate is Al(NO3)3, so there are 9 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
How many atoms are in C8H16?
24: The answer to the number of atoms present in a formula that does not include parentheses is always the sum of all the subscript numbers in the formula plus one for each type of atom shown without a subscript. If the formula does contain parentheses, all the subscript numbers inside the parentheses should be multiplied by the subscript number after the closing parenthesis itself before the sum of all subscripts is taken.
The subscript in a chemical formula refers to the?
The subscript in a chemical formula refers to the _____.
Chemical formula of brick?
Brick is a mixture of a number of substances and so does not have a chemical formula.
What does a subscript following a set of parenthesis in a chemical formula indicate?
The number of units of the polyatomic ions with formulas contained within the parentheses that are present in a formula unit.
How many carbon atoms in cobalt acetate?
The formula for cobalt acetate is Co(C2H3O2)2. According to the formula, there are four carbon atoms in each formula unit. When an ion is in parentheses, you multiply the subscripts inside the parentheses times the subscript outside the parentheses to find the total number of atoms of an element.
How many terms will you have inside the parentheses after you factor out the gcf?
After you factor out the GCF, you will have as many as terms inside the parentheses as you had before.
How many oxygen atoms are there in the formula for aluminum nitrate?
The formula for aluminum nitrate is Al(NO3)3, so there are 9 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
The process of multiplying a number outside a set of parentheses to everything inside the parentheses is called?
The process of multiplying a number outside a set of parentheses to everything inside the parentheses is called distributing or the distributive property. This property is used to simplify algebraic expressions by multiplying the external number to each term inside the parentheses.
How many atoms are in C8H16?
24: The answer to the number of atoms present in a formula that does not include parentheses is always the sum of all the subscript numbers in the formula plus one for each type of atom shown without a subscript. If the formula does contain parentheses, all the subscript numbers inside the parentheses should be multiplied by the subscript number after the closing parenthesis itself before the sum of all subscripts is taken.
How many oxygen atoms are in aluminum chromate?
The formula for aluminum chromate is Al2(CrO4)3, so there are 12 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
How many atoms does a molecule contain?
It depends on the molecule! If you have a molecular formula for a molecule and the formula does not contain parentheses, you can find the number of atoms in it by adding all the subscripts, treating no subscript as the number 1. If the formula does contain parentheses, first multiply any subscript within the parentheses by the subscript at the end of the parentheses, then add these modified numbers to those of any other atoms in the formula that are not in parentheses.
What is the property where you multiply the number on the outside of the parentheses by everything on the inside called?
The distributive property.
The subscript in a chemical formula refers to the?
The subscript in a chemical formula refers to the _____.
Chemical formula of brick?
Brick is a mixture of a number of substances and so does not have a chemical formula.
Does a chemical formula show it solution?
chemical formula is an abbreviation representing the molecules of an element or a compound . The number and kind of the atoms of elements can be understood from the chemical formula . The symbol and number of atoms of each element will be indicated in the chemical formula.
