Why rubber have the same empirical formula as its monomer?
An empirical formula only takes into account the proportions of the elements in a compound. The proportion of elements in a polymer might be the same or similar as the proportion in the monomer from which it is made.
Which could represent the empirical and the formula of a given compound?
The empirical formula is representative for the chemical composition of a compound; the structural formula is representative for the spatial structure of the compound.
Explain why the percent composition of certain compounds are not sufficient to determine the compounds molecular formulas?
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
How do you determine the empirical formula of a metal oxide?
First it is necessary a correct chemical analysis of this compond, with the goal to establish the empirical chemical composition.
What is an example of the emprical formula?
There is not enough information to answer the question

Can you determine the molecular formula of a substance from its percent composition?
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.
What is the importance of percentage composition?
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.
Which could represent the empirical and the formula of a given compound?
The empirical formula is representative for the chemical composition of a compound; the structural formula is representative for the spatial structure of the compound.
Explain how your class's results in this experiment support the law of definite composition?
"The Law of Definite Composition states that the elements in a given compound are always combined in the same proportion by mass."All of the students in our class had different values for the mass of the hydrate and anhydrous salt, but all calculated the same formula for the hydrate. By everyone calculating the same formula for the hydrate, the law of definite composition was proved.

How do you know when to solve for a empirical formula?
If it tells you to find the empirical formula when percent composition is given or if the mass of each element is given in a specific compound.
How law of constant proportion applied in experiment empirical formula of a compound?
percentage of mg
Empirical formulas describe the types of atoms in a compound and their?
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
The empirical formula may not represent the actual composition of a?
The empirical formula is the smallest whole number ratio of different elements in a molecule. The molecular formula has the actual number of atoms of different elements in a molecule
How do you determine the empirical formula of a metal oxide?
First it is necessary a correct chemical analysis of this compond, with the goal to establish the empirical chemical composition.
Do compounds have variable composition?
No. Compounds have a definite composition, therefore they are pure substances. For example, water always has the formula H2O, sodium chloride (common table salt) always has the formula NaCl, and glucose (blood sugar) always has the formula C6H12O6.
