You would look at the chemical formula. The subscripts tell you how many atoms of an element are in one molecule or formula unit.
Examples:
H2O has 2 atoms of hydrogen and 1 atom of oxygen.
C6H12O6 has 6 atoms of carbon, 12atoms of hydrogen, and 6 atoms of oxygen.

∙ 13y agoIf you know the elements in the compound, you can find the mass per mole of the compound, and use Avogadro's Constant (the number of atoms per mole) to find out the number of atoms for a given mass of a compound.
For example, if I have 50g of Copper, this is approximately 0.79 moles of Copper. I multiply Avogadro's Constant, which is approximately 6*10^23, by 0.79, which gives me 4.74*10^23, so I know that there are 4.74*10^23 atoms of Copper present.

Is a compound with the formula C6H12O6 made up of 3 atoms?
Yes. Three different atoms by element, but the count is...... 6 carbon atoms. 12 hydrogen atoms. 6 oxygen atoms. The compound is glucose.
How do you find how many atoms of an element are in a compound if you are only given the name and not the formula?
Draw the structure based on the name. Then count the number of times each atom appears in the structure. Alternately, you can determine the formula from the structure - and then count all atoms of each type.
Is methane gass an element mixture or compound?
methane is a compound as one carbon atoms combines with 4 hydrogen atoms.
Why is the ratio of a different atoms in a compound important?
The ratio of different atoms in a compound important because the compound has to achieve an equilibrium in terms of electrical charge. The net total of charges of the atoms forming a compound must be zero.

What is an atom inventory?
Is a count of the numbers of atoms of each element in a compound or in a chemical reaction.
How many atoms are there in C6H8O7?
This compound contain 21 atoms in the molecule.
What is the ratio of atoms?
A chemical formula gives the number ratio of the different kinds of atoms present in the compound. This means that the ratios are the same if you count in individual atoms, dozens of atoms, or molecules of atoms.
How many different atoms are there in a compound?
Depends on the compound. The formula of that compound will tell you how many atoms are in it. Some compounds are pretty simple, like water. The formula for water is H2O. That means 2 hydrogens and 1 oxygen (no subscript means 1.) So, two different types of atoms for a total of three. Or, you might have a compound with the formula of C8H10N4O2. That's caffeine. Count up all the subscripts for each element and you get a total of 24 atoms in that one. And there are plenty of compounds out there with more than that!

What atoms are found in a compound?
These atoms are from the chemical elements contained in the molecule of this compound.
Is methane gass an element mixture or compound?

What kind of atoms make up the compound iodine?
Iodine is not a compound. It is an element. Therefore, it has its own atoms: Iodine atoms.
What compound is a compound with no combination of carbon atoms?
an inorganic compound
