Subscripts in a molecular formula represent the number of atoms of an element in a molecule?

That's right. When you have a chemical formula, such as SO4, the formula for Sulfate, the subscript means that there are four Oxygen atoms for every one Sulfur atom. Also, when you have really big molecules that are made up of several smaller molecules in them, such as Iron Sulfate, the subscript goes just outside of parenthesis surrounding the smaller molecule's own formula, like this: Fe2(SO4)3

The molecular formula mass of this compound is 210 amu What are the subscripts in the actual molecular formula Enter the subscripts for C H and O?
Element Element's atomic massC : 12H2 : 2(hydrogen's atomic mass is 1 but remember there are two)O : 16Add all the elements atomic mass and then divide the molecular mass by it. After that you only need to multiply all the subscripts of each element to find your answer.12+2+16=30240/30=88(CH2O) = C8H16O8
What is a molecular formula?
The molecular formula specifies the actual number of atoms of each element in a molecule.
Molecule of oxygen?
The element oxygen has two molecular forms: O2 for 'plain' oxygen gas and O3 for ozone
What specifies the actual number of atoms of each element in one molecule of a compound?
This is specified by the subscripted number directly next right-down to the atom's symbol.Example: Sulfuric acid: H2SO4 has 2 atoms of Hydrogen, 1 atom of Sulfur and 4 atoms of Oxygen per molecule H2SO4
Is chlorine a molecular compound?
No. It's a molecular element.
In a chemical formula what do subscripts mean?
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.

What is the subscripts of a chemical equation?
The amount of atoms of each element that make up a single molecule.
What do the little numbers next to the letters in the formula of a molecule represent?
they represent the number of protons and electrons.
What are lowered numbers in a compounds formula?
The lowered numbers are called subscripts, and represent either the number of atoms of the element they follow in a molecular formula, or the ratio of ions in an ionic compound. For example, the molecular formula for a water molecule, H2O, indicates that there are two hydrogen atoms and one oxygen atom per molecule. Also, the formula unit for the ionic compound calcium chloride, CaCl2, indicates that in the ionic compound, the ratio of calcium ions to chloride ions is 1 to 2.
What is the molecular formula for argon?
Argon is an element, not a molecule, and as such does not have a molecular formula, but rather a symbol - "Ar".
Is nitogren a atomic or molecular element?
Nitrogen has a diatomic molecule (N2).
What is a molecular formula?
The molecular formula specifies the actual number of atoms of each element in a molecule.
Is nitrogen an element or molecule?
Nitrogen is both an element and a molecule. In molecular form, Nitrogen forms a binary molecule N2 with a triple bond between the two Nitrogen atoms.
Molecular formula for sodium?
Sodium is a chemical element not a molecule; the symbol is Na.
Chemical formulas represent the number and element of each type of atom in?
Chemical formulas represent the number and element of each type of atom in a molecule.
How are chemical formulas written do they use superscripts or subscripts?
Chemical formulas are written with the chemical symbol of each element followed by a subscript. If no subscript is written, it is understood to be 1. In a molecular formula, the subscripts indicate the number of atoms of each element that are present in one molecule. In a chemical formula for an ionic compound, the subscripts represent the lowest whole number ratio of ions in the compound.
