### How are molecular and empirical formulas related?

Molecular formula is the integral multiple of Empirical formula.

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

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

### 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 do you calculate Molecular formula from empirical formulaWhat could you do with that information to determine that the empirical and molecular formulas are related to one another by a factor of 6?

In order to find molecular formula from empirical formula, one needs to know the molar mass of the molecular formula. Then you simply divide the molar mass of the molecular formula by the molar mass of the empirical formula to find out how many empirical formulae are in the molecular formula. Then you multiply the subscripts in the empirical formula by that number.

### 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.

### 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.

### 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.

### How are the emprical and molecular formulars for a compound related?

The empirical formula is the lowest whole integer representation of the molecular formula. For example, the empirical formula for C6H12O6 would be CH2O.

### What is the empirical formula for calcium phosphate?

Ca3P2 or Ca3(PO4)2 See related question below for more details on how to find empirical formulas.

### What is an empirical formula?

The chemical formula in which the subscripts are given in the smallest ratio.

### What is the difference between a formula unit and a molecular formula?

Molecular formulas refer to covalently bonded substances (molecules). The molecular formula shows the exact number of atoms of each element present in the smallest unit of the substance. For example, benzene is a molecule composed of six carbon and six hydrogen atoms and has a formula C6H6.A formula unit refers to ionic compounds and network solids (both are crystals). Because in ionic crystals each ion is electrostatically bonded to every oppositely charged nearest neighbor, the ions in the whole crystal can be thought of as part of one single bonded entity. It is the same with network solids except that the bond is covalent. So rather than using a formula that shows all of the elements present in any one particular crystal, the formula unit shows the elements present in the smallest whole number ratio. In a common example, sodium chloride, the formula unit is NaCl since sodium and chloride are present in the crystal in a 1:1 ratio. The NaCl crystal itself, however, would have >>quintillians each of Na and Cl if it was big enough to see with the unaided eye. It is important to not confuse formula units with emprical formulas. Emprical formulas are simply the lowest whole number ratio of elements in a compound. Formula units are always empirical, whereas molecular formulas are usually not. For example, the empirical formula of benzene, C6H6, is CH, since there is a 1 to 1 ratio of C to H. Note that several molecules can have the same empirical formula. For example acetylene, with molecular formula C2H2, also has the same empirical formula as benzene, even though the two molecules are very different! Water, H2O, is an example of a molecular formula that is also empirical.A formula unit is the symbolic representation of an ionic compound or network solid, and a molecular formula is the symbolic representation of a molecular compound.See the Web Links and Related Questions links for more information.
