A chemical formula used to show the number and types of atoms present in a molecule is referred to as what?
A chemical formula that shows the number and types of atoms in a molecule is known as a molecular formula. Molecular formulas are written by writing the symbol for each element followed by a subscript to show the actual number of atoms in the molecule.
Do the subscripts in a chemical formula represent the relative mass of each atom in a chemical compound?
It usually represent the amount of atoms in a molecule, i.e. Na2CO3 + 2HCl --> 2NaCl + CO2 +H2O So, in the first compound, there are 2 sodium atoms, one carbon atom and 3 oxygen atoms. In water, there is one hydrogen atom and 2 oxygen atoms..
How many lead atoms are in the following Pb3PO4?
In each MOLECULE of Pb3PO4 there would be 3 lead atoms, but Pb3PO4 is not a correct formula. The formula for lead phosphate would be Pb3(PO4)2. There are still 3 lead atoms per molecule of the compound.
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 O atoms are in Zn(ClO2)2?
As would be more apparent from its properly written formula, Zn(ClO3)2, each formula unit contains 6 oxygen atoms, the product of the subscript immediately following the oxygen atomic symbol and the subscript following the parenthetical formula of the chlorate polyatomic ion of which the oxygen atoms present are a part.
How many atoms of each element are there in 2Na2CO3?
6. 2 sodium, 1 carbon, and 3 oxygen.

How many atoms of each element are shown in the formula for calcium carbonate?
There are five atoms
How does a complete structural formula differ from a condensed structural formula?
------ The condensed structural formula is simply a shortened version of the complete structural formula. -------The complete formula indicates all of the carbon and hydrogen atoms. The condenced formula groups the hydrogen atoms with each of the carbon atoms.
What tells how many of each type of atom are found in an actual molecule of that substance?
This is the subscripted number of each atom in the chemical formula.Example: sodium carbonate - Na2CO3.The molecule contain 2 sodium atoms, 1 carbon atom and 3 oxygen atoms.
How many hydrogen atoms are containedin the formula for ammonium sulfide?
The formula for ammonium sulfide is (NH4)2S. Therefore, each formula unit contains 8 hydrogen atoms.
How many atoms are in 2AL2O3?
The 2 in front means 2 formula units, or 2 moles of the compound Al3O2. So you would multiply the 2 in front times the subscripts in the formula unit Al3O2. In the formula unit Al3O2, there are 5 atoms. Multiply that by the 2 in front and you get 10 atoms.
How many oxygen atoms does the compound Ba(NO3) HAVE?
There is no such compound as BaNO3. The correct formula for barium nitrate is Ba(NO3)2 and in this case, each formula unit would have 6 x 6.02x10^23 atoms of oxygen
How does the presence of a coefficient affect the number of atoms of each type in the formula that it prescedes?
You multiply the coefficient times the subscripts (number of atoms of each type in the formula) to get the total number of atoms of each element. For example: 2CO2 means 2 carbon atoms and 4 oxygen atoms (No subscript is understood to be 1.) 3C6H12O6 means 18 carbon atoms, 36 hydrogen atoms, 18 oxygen atoms
What is the number of atoms in CaS?
This compound is calcium nitrate. Each formula unit will contain 9 atoms.
