You start with the mass of the compound. This you divide by the total molecular mass of the compound (the Atomic Mass of 1 molecule) and you multiply this by the amount of atoms 1 molecule consists of.
First, go to your Periodic Table of Elements to get the atomic weight of each constituent element, then multiply that by the number of atoms of that element in the compound in question, add up all the resulting weights for all the constituent elements, and presto! You have the weight of the compound, per mole.
Take 1/2 the density and multiply it by 2 times the atomic radius. all info is given on the reference table
C9h12
the formula weight of a compound is determined by adding up the individual weights of every atom in the compound. For example the formula weight of Magnesium Bromide (MgBr2)= 24 + 2(80) = 184
This compound is UF6. Atomic weight of uranium: 238,02891 Atomic weight of fluorine: 18,9984032 Molecular mass of UF6: ca. 352,04121
Look at the Periodic Table.
Organic formula is a formula that shows an organic compound and its molecular arrangement.

the formula weight of a compound is determined by adding up the individual weights of every atom in the compound. For example the formula weight of Magnesium Bromide (MgBr2)= 24 + 2(80) = 184
the sum of the atomic weights for all the atoms in the formula
To find this you also need to know the chemical (or formula) weight of one mole of the compound in grams per mole (so about which compound you're talking about).
Percent composition can be used to calculate the percentage of an element/compound in a mixture. From the percent composition, you can also find the empirical formula. And from the empirical formula you can find the actual molecular weight.

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.

SO3
NaCl
To find the formula weight you have to add each elements mass together. The formula for this compound is CaSO3. Ca:40.08 S:32.07 O:3X16=48 Total= 120.15 <---- this is the formula weight.
Zinc's weight is 65.4, and Chlorine's weight is 35.5. Add the weight of the two chlorine atoms to one zinc atom. The resulting formula is ZnCl2.
