get your question to a grammar checker. As a 13 year old i have spotted these mistakes and it is apaling to think that this stuff is actually considored english.

What is an empirical formula for the molecule?
An empirical formula is a chemical formula containing only the number of atoms why is formed (ex.: C6H12), without any indication about the structure.
What is the properly written empirical formula of a compound of molecular formula C6H12 with a molar mass equal to 84.16 gram per mol?
The information about the actual molar mass is superfluous. Given any molecular formula, the corresponding empirical may be obtained by dividing all the subscripts in the molecular by the largest integer that yield an integer quotient for each subscript. In the given formula, the empirical formula is CH2.
Can the empirical formula be used to calculate the percent composition of a compound?
The empirical formula is the simplest ratio of the elements within a compound. Therefore, it can be used to calculate the percentage of an element within a compound. For example, the empirical formula for sodium chloride is NaCl. From this, we can see that the ratio of sodium ions to chloride ions is 1Na : 1Cl. Therefore, a sodium chloride molecule is composed of 50% sodium and 50% chloride.
Why some compounds have molecular and empirical formula?
The concept of empirical formulas apply to ionic compounds. You write the action first, the anion second, and use the minimal amount of atoms possible to make a neutral compound. A molecular formula would be the formula without necessarily the minimum amount of atoms.
What is the enzymatic breakdown of any type of food molecule by the edition of a water molecule to each molecular bond?
pepsin
What is the empirical formula for a compound whose molecular formula is C2Cl6?
What you have listed is the molecular formula, C6H4Cl2, the molecular formula is a multiple of the empirical formula in this case being C3H2Cl.
What molecular formulas are an empirical formula?
Any molecular formula where the subscripts do not have a common factor that can divide them all. For example: CH4 (methane) is a molecular formula that is also an empirical formula because there is no number (other then one) that can divide both the 4 and the 1. Take ethane as another example. It hasn't the empirical formula which is similar to the molecular formula.
What molecular formulas are also an empirical formula?
Any molecular formula where the subscripts do not have a common factor that can divide them all. For example: CH4 (methane) is a molecular formula that is also an empirical formula because there is no number (other then one) that can divide both the 4 and the 1. Take ethane as another example. It hasn't the empirical formula which is similar to the molecular formula.
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.
What is the empirical formula for butane?
Well you know that Butanoic Acid's Molecular formula is C3H7COOH, and Empirical formula is a compound showig the simplest ratio of numbers of atoms of each element in the compound. Now the question is, can you simply C3H7COOH ? Nope! Then the Empirical formula is also C3H7COOH
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.)

An empirical formula is a chemical formula containing only the number of atoms why is formed (ex.: C6H12), without any indication about the structure.

What is relationship between empirical formula and formula unit?
A formula unit includes the correct number of each kind of atoms present in a molecule of a covalently bonded compound, but an empirical formula does not necessarily do so. An empirical formula is reliable with respect to the ratios between each kind of atom, but the molecule may contain any positive integral number of empirical formulas, including one.
The molecular formula for sucrose is C11H22O11. How would the empirical formula of sucrose be obtained from this information?
The empirical formula is the smallest unit which shows the different atoms in their correct ratios. You find it by taking out any common factor from the numbers. In this case all three numbers divide by 11, so the empirical formula is CH2O. In practice, we usually determine the empirical formula from experiment (hence the name), then use it with other information to derive the molecular formula.
Can the empirical formula be used to calculate the percent composition of a compound?
The empirical formula is the simplest ratio of the elements within a compound. Therefore, it can be used to calculate the percentage of an element within a compound. For example, the empirical formula for sodium chloride is NaCl. From this, we can see that the ratio of sodium ions to chloride ions is 1Na : 1Cl. Therefore, a sodium chloride molecule is composed of 50% sodium and 50% chloride.
