Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.

How do you write the molecular formula for 2-methyl-1-butanol?
C5H12o
Who invented C4 bomb?
No single individual or even group of individuals invented C4, it evolved in a series of changes and improvements due to changing military requirements and operational conditions over time.C4 was a reformulation of C3 which was a reformulation of C2 which was a reformulation of C1 which was developed during World War 2 as an improvement on the Composition B and Composition A explosives that the US military was then using. Note: C1 through C4 are Composition C explosives. All three (Composition A, Composition B, and Composition C) explosives have numbered revisions, C4 is just the 4th revision of the basic Composition C formula.The original US Composition A formula was adapted from a British formula for plastique explosive, which was then being supplied to the French resistance (thus the spelling "plastique").
What is the formula for chemical energy?
Energy has no chemical formula as it is not a chemical.
Formula for capacity of a cylinder?
Formula for a cylinder is pi*radius2*height.
What set up a formula to determine the number of immigrants allowed in the united stated?
The Immigration and Nationality Act of 1952, as amended, establishes the framework for determining the number of immigrants allowed in the United States. The formula includes factors like family-sponsored preferences, employment-based preferences, diversity visa program, and humanitarian provisions. The specific numerical limits for each category are determined annually by the U.S. Congress through the appropriations process.
Explain why the percent composition of certain compounds are not sufficient to determine the compounds molecular formulas?
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
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)
What does a compound formula tell you?
A compound formula, or molecular formula, tells you about the chemical composition of the substance in terms of the number of atoms of that element that are present. From there, the empirical formula may also be derived by simplifying the molecular formula, as well as its structural formula.
To determine the formula of a new substance one of the first steps is to find?
The chemical formula is determined by chemical analysis of the components.
Derivation of formula?
Formula regards the composition of a substance. In Chemistry molecular formula is derived by the composing elements and their atomic quantities. For example the chemical formula of water (H2O) is two hydrogen and single oxygen.
Which substance shows a substance that is not molecular?
A formula unit.
Which formula show a substance that is not molecular?
A formula unit.
What do you need to calculate the percent-age composition of a substance?
The molecular formula of the compound can be calculated from the composition of element in a compound. The next steps are involved in the calculation of percentage of every element in a compound.
What is the molecular formula based upon?
The formula is based on the chemical composition of the molecule.
Determine the molecular formula for the unknown if the molecular mass is 60.0 amu and the empirical formula is CH2O.?
C2H4O2=molecular formula, basically you multiply the empirical formula by 2.
What is the combination of letters and numbers used to represent a substance?
A molecular formula contains the atomic composition by element and their quantities. For example H2O is the molecular formula for water. The formula indicates that there are two atoms of hydrogen (H) and one oxygen (O) in each water molecule. Through the molecular formula molar mass can further be derived. In the case of water is 18-grams per mole.
What does a formula look like?
In chemistry a molecular formula is used to illustrate the elemental composition and atomic quantities of a given molecular substance. A molecular formula is in the format of an elements symbol followed by a subscript of the # of atoms of each. For example water (chemically also known as dihydrogen monoxide) is H20 with the H and 2 symbolizing 2 atoms of hydrogen and a single oxygen.
