The empirical formula is CH2O. To find the molecular formula, you need to calculate the empirical formula weight (30 g/mol) and divide the molecular mass (180.0 g/mol) by the empirical formula weight to get 6. This means the molecular formula is (CH2O)6, which simplifies to C6H12O6, the molecular formula of glucose.

The combustion data for an unknown compound containing carbon hydrogen and oxygen was analyzed and the empirical formula for the unknown was found to be C3H5O The molar mass of the unknown was found?
To find the molecular formula from the empirical formula (C3H5O) and molar mass, you need to calculate the molar mass of the empirical formula. Then, divide the molar mass of the unknown compound by the molar mass of the empirical formula to get a ratio. Finally, multiply the subscripts in the empirical formula (C3H5O) by this ratio to determine the molecular formula of the unknown compound.
How are the empirical and molecular 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.

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.
Can an empirical formula be triple its molecular formula?
No, an empirical formula represents the simplest whole-number ratio of atoms in a compound, while a molecular formula shows the actual number of each type of atom in a molecule. Therefore, an empirical formula cannot be triple its molecular formula.
Can the empirical formula of a compound be triple its molecular formula?
No, the empirical formula represents the simplest whole-number ratio of atoms in a compound, while the molecular formula shows the actual number of each element present in a compound. Therefore, the empirical formula cannot be triple the molecular formula.
What is the empirical formula for a compound whose molecular formula is C2Cl6?
The empirical formula for a compound is the simplest whole number ratio of the elements present in the compound. In this case, the empirical formula for a compound with a molecular formula of C2Cl6 is CH3Cl.

To find the molecular formula from the empirical formula (C3H5O) and molar mass, you need to calculate the molar mass of the empirical formula. Then, divide the molar mass of the unknown compound by the molar mass of the empirical formula to get a ratio. Finally, multiply the subscripts in the empirical formula (C3H5O) by this ratio to determine the molecular formula of the unknown compound.
What represent a molecular compound?
This is the chemical formula (empirical formula) or the formula unit of this compound.
What is the molecular formula of a compound if the weight is of a unit of the compound is 120 and the empirical formula is C3H4?
To find the molecular formula, you first need to calculate the empirical formula mass of C3H4. C3H4 has an empirical formula weight of 40 g/mol. If the molecular weight is 120 g/mol, then the molecular formula would be 3 times the empirical formula, so the molecular formula would be C9H12.
How do you find molecular fomula?
To find the molecular formula of a compound, you need to know its empirical formula and molar mass. Divide the molar mass of the compound by the molar mass of the empirical formula to find the "multiplication factor." Multiply the subscripts in the empirical formula by this factor to get the molecular formula.
What is the empirical formula of a compound with the molecular formula C 12 H 8?
The empirical formula of a compound with the molecular formula C12H8 is CH2. This is determined by dividing the subscripts in the molecular formula by the greatest common factor (in this case, 4) to obtain the simplest whole-number ratio of atoms in the compound.

What is the empirical formula for the compound below C10H25O5?
The empirical formula for the compound with the molecular formula C10H25O5 is C2H5O. This is obtained by dividing all subscripts in the molecular formula by the greatest common factor.
Which compound has the empirical formula ch2o?
CH2O is not only the empirical but also the molecular formula for formaldehye. It is also the empirical but not the molecular formula for hydroxyacetaldehyde, acetic acid, methyl formate, 1,3-dihydroxyacetone, and many other compounds.
What is the molecular formula of a compound with the empirical formula NH2Cl and molar mass of 51.5g mol?
The empirical formula NH2Cl has a molar mass of 51.5 g/mol, so the molecular formula can be determined by finding the ratio of the molar mass of the molecular formula to the molar mass of the empirical formula. The molecular formula of the compound is therefore NH2Cl2.
