How does one determine a molecule formula from the empirical formula?

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.


What would be the empirical formula for glucose C6H12O6?

The empirical formula of glucose is the formula which has the lowest ratio. You can divide all three elements by 6 to give: CH2O.


Choose the empirical formula?

To determine the empirical formula of a compound, you need the molar masses of its elements and their ratio in the compound. Calculate the ratio of the elements in terms of whole numbers, which will give you the empirical formula.

An empirical formula give information about the chemical composition of a compound. Example: tetracycline with the empirical formula C22H24N2O8 has the following composition: - carbon 59,44 % - oxygen 28,81 % - nitrogen 6,30 % - hydrogen 5,45 % If you're with plato the answer is ratios


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.
