Yes it does.
Ex.: C6H12O6 is glucose, or sugar. To find the Atomic Mass, you must add up all the masses of each element like so:
C=12.01 mol.g
H= 1.01 mol.g
O= 16.00 mol.g
(12.01 x 6) + (1.01 x 12) + (16.00 x 6) = 180.18 mol.g is glucose's atomic mass. This can be done with any compound if you have the empirical formula, and the weights for the elements found on the Periodic Table.

How to calculate empirial formula from molecular formula?
To calculate the empirical formula from a molecular formula, divide the subscripts in the molecular formula by the greatest common factor to get the simplest ratio of atoms. This simplest ratio represents the empirical formula.
What additional information do you need to determine the molecular formula?
To determine the molecular formula, you need the molecular weight of the compound, the empirical formula, and any information about the compound's structure or the number of atoms of each element present. Additionally, knowing the types of elements involved can also help in calculating the molecular formula accurately. If the empirical formula is known, the ratio of the empirical formula's mass to the molecular weight will help in finding the actual molecular formula.
An unknown sample with a molecular mass of 180.0g is analyzed to yield 40 percent C 6.7 percent H and 53.3 percent O What is the empirical formula and the molecular formula of this compound?
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.
How do you find out the volume when you have molecular weight and wt of compound?
To calculate the volume of a compound when given its molecular weight and weight, you need to first convert the weight to moles using the molecular weight.

What is the molecular weight of dipotassium oxide?
The molecular formula of dipotassium oxide is K₂O. To calculate its molecular weight, you sum the atomic weights of its constituent elements: potassium (K) has an atomic weight of approximately 39.1 g/mol, and oxygen (O) has an atomic weight of about 16.0 g/mol. Therefore, the molecular weight of K₂O is (2 × 39.1) + (1 × 16.0) = 94.2 g/mol.
