To determine the subscript of an element in a molecular formula the empirical mass must be multiplied by the actual mass?
The actual mass must be divided by the empirical mass. This was derived from the following equation: (subscript)(empirical formula) = (molecular formula) subscript = (molecular formula)/(empirical formula)
What type of formula is based on the actual number of atoms that comprise a molecule of that compound?
This is called an empirical formula.
How may a chemical formula differ from an empirical formula?
CH2O = Empirical formula for carbohydrates. The ratios of the diggerent atoms are shown here and with a skeleton formula. C6H12O6 - Glucose, the actual carbohydrate with a full elemental complement.
Empirical and molecular formulas?
The Empirical formula of Al2Br6 is AlBr3.
What is an empirical formula c4h8 c2h4 ch c2h2?
CH2 is the empirical formula for C4H8 because it is an alkene and the empirical fomula for ALL alkenes are C(n)H(2n) n being the number of molecules!!! (^-^)
What is the importance of percentage composition?
Percent composition can be used to calculate the percentage of an element/compound in a mixture. From the percent composition, you can also find the empirical formula. And from the empirical formula you can find the actual molecular weight.

What is the emperical formula for C6H12?
Empirical formula gives the proportions of the elements present in a compound but not the actual numbers or the arrangement of atoms. The empirical formula for C6H12 is CH2.
How can you find the molecular formula of a compound when its percentage composition is given?
Yes, if you have some additional information, such as the molecular weight. For instance, the molecules C2H4 and C4H8 have exactly the same percent composition, but they are very different molecules. So you need some other information to tell them apart than the percent composition.Answer ExpandedThis is kind of a trick question. By knowing the percent composition, you would easily be able to determine its empirical formula, but molecular formula is a bit different. The molecular formula is the actual number of atoms in a molecule, so in order to find the specific molecular formula of a substance, you would also need to know how many grams there is of that substance.(This explains the difference between C2H4 and C4H8)

Empirical and molecular formulas?
The Empirical formula of Al2Br6 is AlBr3.
How are the empirical and molecular formulas for a compound. Related?
A molecular formula is identical to the empirical formula, and is based on quantity of atoms of each type in the compound.The relationship between empirical and molecular formula is that the empirical formula is the simplest formula, and the molecular can be the same as the empirical, or some multiple of it. An example might be an empirical formula of C3H8. Its molecular formula may be C3H8 , C6H16, C9H24, etc. Looking at it the other way, if the molecular formula is C6H12O6, the empirical formula would be CH2O.

CH2 is the empirical formula for C4H8 because it is an alkene and the empirical fomula for ALL alkenes are C(n)H(2n) n being the number of molecules!!! (^-^)
What is the contrast between molecular formulas and empirical formulas?
The empirical formula of a compound shows the lowest whole number ratio of the elements in that compound; AKA simplest formula. The molecular formula describes the number of atoms of each element that make up the molecule or formula unit; AKA actual formula
What is the molecular formula for sodium hydroxide?
For sodium oxide, the empirical formula is the same as the formula unit, Na2O. (If any formula unit or molecular formula contains an atomic symbol with no following subscript, the empirical and actual formulas will be the same.)
What is the difference between empirical and molecular formula?
An empirical formula is one that shows the lowest whole number ratio of the elements present. The molecular formula shows the composition of the molecules. An example is phosphorus pentoxide, P2O5 empirical formula, P4O10 molecular formula.
