How many atoms are represented in a formula CaCO3?
5 Atoms
How many atoms of element O are represented in the formula?
Depending on the formula ! Two atoms in PbO2, three atoms in Al2O3, etc.
What does the subscriptthe little number represent on the chemical formula ex O2?
It means there's that number of atoms in a particle of the substance represented by the entire formula. For example, in CO2, there are 2 oxygen atoms. The absence of a subscript after the C means there is 1 carbon atom.
What is the empirical formula of MgO?
MgO is an ionic compound and all the ionic compounds are represented by their emperical formula because actual no of atoms can not be represented due to a very huge crystal formation.(crystal lattice).
What number of moles of polonium represented by 3.18 and times 1024 atoms of polonium?
The number of moles is 0,528.
How many atoms are represented in the formula?
A chemical formula is the representation of a molecule of a chemical compound; all the atoms from the molecule of this compound need to be represented in the formula.

How many atoms of element O are represented in the formula?
Depending on the formula ! Two atoms in PbO2, three atoms in Al2O3, etc.
What are the total number of hydrogen atoms represented in the following formula C6H10(OH)6?
16 The subscript applies to each of the atoms within the parentheses.
There are three atoms of iodine represented in the formula NaIO3?
false

Why compounds are represented in a formula unit?
Compounds are represented by a formula unit to show the simplest ratio of atoms or ions. This unit repeats throughout any amount of the compound.
How many atoms of element Al are represented in the formula Al2 SO4 3?
Depending on the formula of the chemical compound containing aluminium.
What is a molecule represented by?
I didn't recall that there was a term, it's just a group of atoms. A Molecule is a scientific term as it is.
What is the empirical formula of MgO?
MgO is an ionic compound and all the ionic compounds are represented by their emperical formula because actual no of atoms can not be represented due to a very huge crystal formation.(crystal lattice).
If empirical formula is C2H5 what is molecular formula?
The molecular formula would have to be C4H10 as the number of hydrogen atoms cannot exceed 2+2X where X is the number of carbon atoms.
What is the number written in front of a chemical formula?
The number written in front of a chemical formula is called the coefficient. This represents the number of molecules of the substance in the chemical formula. For example, 8SO3 tells you that there are 8 molecules of SO3 or sulfur trioxide.
