### What is the molecular formula of a compound that has a molecular mass of 46 and an empirical formula of No2?

The molecular formula is the same as the empirical formula, NO2. The compound NO2 has a molar mass of 46g/mol, so the empirical and molecular formulas are the same.

### How is molecular formula C3H6 and molecular formula C6H12 related?

Both formulas are possible molecular formulas for the same empirical formula, CH2.

### Why do you use both empirical and molecular formula?

Molecular formulas are used the most often, but empirical formulas do help at times. Often it's just to simplify the molecular formula, but this simplification can often tell you if it's in the same chemical family as other compounds and such.

### What is the empirical formula for methane?

The same as its molecular formula; CH4. See related question below for more details on how to find empirical formulas.

### 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.

### Can several compounds have the same empirical but have different molecular formulas?

Yes they can. For example CH2O is the empirical formula for both formaldehyde(CH2O) and glucose(C6H12O6)

### What is the difference between empirical and molecular formula?

Empirical formulas show the simplest whole number ratio of these atoms. Molecular formulas show the actual ratio of atoms in the compound. For example: Glucose is the a simple sugar whose molecular formula is C6H12O6 Its empirical formula would be CH2O which would be its molecular formula divided by the smallest whole number. Chemical Name Hydrogen peroxide Empirical Formula HO Molecular Formula H2O2 chemical name Benzene empirical formula CH molecular formula C6H6 remember that several compounds can have the same empirical formula

### What is the empirical formula for nitrogen dioxide?

The empirical formula for nitrogen dioxide is the same as its molecular formula - NO2. See related question below for more details on how to find empirical formulas.

### What steps are used to convert an empirical formula into a molecular formula?

A molecular formula is the same as or a multiple of the empirical formula. The first step will be to assume exactly 100 grams of the substance, then convert each of these masses to moles,

### What is the empirical formula for sodium oxide?

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.)

### Is the CCL4 empirical formula or molecular formula?

CCl4 is the molecular formula for carbon tetrachloride. It is the same as its empirical formula.

### How are the empirical and the molecular formulas for a compound related?

the empirical formula only gives the amount of each element as a ratiothe molecular formula gives the actual number of atoms of each element in a molecule of the compoundFor example these compounds all have the same empirical formula (CH2) but different molecular formulas: ethylene C2H4butene C4H8cyclohexane C6H12cyclooctane C8H16cyclodecane C10H20etc.

### Simplest empirical formula for allicin?

C6H10OS2. Molecular and empirical are the same for Allicin.

### What are the empirical and molecular formulas for sucrose?

MF C12H22O11 EF same notice since 11 is prime no number will divide all

### Can an empirical formula be triple its molecular formula?

Yes, it is possible for an empirical formula to be the same as the molecular formula. For example, Lactic acid's molecular formula is C3H6O3, which would make its empirical formula CH2O.

### What is the empirical formula for Ibuprofen?

C13H18O2 Is the empirical formula. It has the same molecular formula too.

### What is the empirical formula for K3PO4?

In this case, the empirical formula and the molecular formula are the same and it is K3PO4.

### When are the empirical and molecular formulas the same?

If one of the atoms is already at its smallest amount. i.e. CH4 would be the same for both, while C2H8 would also have an empirical formula of CH4 though. H2O --&gt; H2O etc.

### What is the empirical formula of hexane?

The molecular formula of hexane is C6H14. The empirical formula is the same as the molecular formula after division of all subscripts in the molecular formula by the highest integer that produce an integer quotient from each subscript in the molecular formula. Therefore, the empirical formula of hexane is C3H7.

### Can empirical formula be the same as the molecular formula?

An empirical formula may or may not be the same as a molecular formula. The empirical formula of a compound shows the smallest whole-number ratio of the atoms compound. The molecular formula tells the actual number of each kind of atom present in a molecule of the compound.
