Multiply each element by the subscript for that element for each element in a molecule. When there is no subscript, it is understood to be 1.
H2O: 2 x H, 1 x O = 3 atoms
CO2: 1 x C, 2 x O = 3 atoms
C2H6: 2 x C, 6 x H = 8 atoms

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 script number tells of the preceding element in the compound?
The subscript number after the preceding element in a compound tells how many atoms of that element are in a molecule or formula unit of the compound. For example, the molecular formula for water, H2O indicates that there are 2 atoms of hydrogen and 1 atom of oxygen in one molecule of water. The formula unit for the ionic compound calcium chloride, CaCl2, indicates that there are 1 calcium ion and 2 chloride ions in a formula unit of calcium chloride.
What does C3H8 tell about a molecule of propane?
The formula tells how many atoms of which elements are found in a molecule of propane. It indicates that there are 3 atoms of carbon and 8 atoms of hydrogen in a molecule of propane.
What is importance of naming chemical formula?
A compound is a substance made up of a definite proportion of two or more elements. A chemical formula tells us the number of atoms of each element in a compound. It contains the symbols of the atoms of the elements present in the compound as well as how many there are for each element in the form of subscripts
How many atoms of carbon are in just one molecule of C8 H10 N4 02?
The subscript 8 tells you that there are 8 atoms of carbon in one molecule.
What type of number after a chemical symbol tells how many atoms are in a single molecule?
The subscript, the little number below and after the element, tells how many atoms are in a single molecule.
What does a subscript tell us about an element in a compound?
In a molecular formula, the subscript tells us the number of atoms of the element that are present in one molecule of the compound. For instance,H2O tells us that there are two hydrogen and one oxygen atom per molecule of water. As for ionic compounds, it tells us the number of atoms present in one formula unit of the compound.
What is the smallest piece of matter a compound can be broken into and still have the same properties?
Once, we thought the answer to this was atoms. Better technology now tells us that there are things within atoms, and things within them. Thus, particles like quarks and gluons are the smallest pieces of matter something can be broken down into.
What does a chemical formula of a substance tell us?
It tells what elements are present in a molecule and how many atoms of each element are present.
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 a compound formula tells about compound'?
It tells what elements are in a compound and the number of each type of atom in each molecule/formula unit.
Is cobalt II chloride a single atom?
As the name tells you, it consists of atoms of cobalt and chlorine. More than one atom in that molecule.
What does percent composition tell you about a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What script number tells of the preceding element in the compound?
The subscript number after the preceding element in a compound tells how many atoms of that element are in a molecule or formula unit of the compound. For example, the molecular formula for water, H2O indicates that there are 2 atoms of hydrogen and 1 atom of oxygen in one molecule of water. The formula unit for the ionic compound calcium chloride, CaCl2, indicates that there are 1 calcium ion and 2 chloride ions in a formula unit of calcium chloride.
The name dinitrogen tetroxide tells you that this compound contains?
The name Dinitrogen tetroxide tells you that the compound contains two nitrogen atoms and four oxygen atoms.
What does C3H8 tell about a molecule of propane?
The formula tells how many atoms of which elements are found in a molecule of propane. It indicates that there are 3 atoms of carbon and 8 atoms of hydrogen in a molecule of propane.
