you must know the molar mass! you need to get the empirical formula first too.
To determine the molecular formula of a compound with a molecular mass of 132 amu, you would need additional information such as the elements present in the compound and their respective atomic masses. Without this information, it is not possible to determine the molecular formula.
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.
The density or some other information must be given that allow you to find the molar mass. Calculate the empirical formula mass. Divide molar mass by empirical formula mass. This answer is multiplied by all subscripts of the empirical formula to get the molecular formula.
To determine the molecular structure of a specific compound using the organic compounds calculator, input the chemical formula of the compound into the calculator. The calculator will then analyze the formula and provide information on the molecular structure, including the types and arrangement of atoms in the compound.
molar mass of unknown/molar mass of empirial = # of empirical units in the molecular formula. Example: empirical formula is CH2O with a molar mass of 30. If the molar mass of the unknown is 180, then 180/30 = 6 and molecular formula will be C6H12O6
the empirical formula and the molar mass
To determine the molecular formula of a compound with a molecular mass of 132 amu, you would need additional information such as the elements present in the compound and their respective atomic masses. Without this information, it is not possible to determine the molecular formula.
C6H12O3 is a molecular formula that contains 54.5% C, 9.1% H, and 36.4% O and has molar mass of 132 amu.
The molecular formula of a compound can not be determined solely based on its molar mass. In this case, without additional information, it is not possible to determine the molecular formula of the compound CH2.
You can't without more information. You cannot go from the molecular weight of a compound to its formula without more information about what atoms it contains.See the Related Questions link to the left for a more detailed discussion of this.

To determine the molecular formula, you would need the molar mass of the compound. With the molar mass, you can calculate the empirical formula mass and then determine the ratio between the empirical formula mass and the molar mass to find the molecular formula.
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.
The empirical formula C2H3 has a molecular mass of 27 (C: 12, H: 1). To determine the molecular formula with a molecular mass of 54, the molecular formula would simply be double the empirical formula, so the molecular formula would be C4H6.
There are 4 step to determine molecular formula, which are given bellow Step:1:- Find empirical formula Step:2:- Find empirical formula mass Step:3:- Find n n=molecular mass/empirical formula mass Step:4:- now find molecular formula to find molecular formula molecular formula(empirical formula)n
