Say you have 100 grams of the compound. If so, then you would have 3.1 grams H, 31.5 grams P, and 65.4 grams O. Convert these to moles:
3.1 grams H ÷ 1.01 grams/mol = 3.07 moles H
31.5 grams P ÷ 31.0 grams/mol = 1.02 moles P
65.4 grams O ÷ 16.0 grams/mol = 4.09 moles O
Divide each of these by the smallest number, which is 1.02:
3.07 ÷ 1.02 = 3
1.02 ÷ 1.02 = 1
4.09 ÷ 1.02 = 4
These are your ratios. The empirical formula is then H3PO4

P underscore 2 O underscore 3
Is phosphorous acid an element?
The empirical formula for phosphoric acid is H3PO4. Its molecular formula is P2O5·3H2O. It is composed of the elements hydrogen, phosphorus and oxygen. Most solutions of phosphoric acid are composed of some amount of H3PO4 in water, H2O.For more information about phosphoric acid, see the Web Links to the left.
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
What is the compound that has an empirical formula of CH2?
C12h24
Can the empirical formula of a compound be triple its molecular formula?
No: The molecular formula is never smaller than the empirical formula.
What is the empirical formula of the compound that is 75 carbon and 25 hydrogen?
The empirical formula of a compound is the simplest whole number ratio of the elements in the compound. In C75H25, the ratio of carbon to hydrogen is 75:25, which is equal to 3:1. Thus, the empirical formula is C3H.
What is the empirical formula for a compound that is 43.6 percent phosphorus and 56.4 percent oxygen?
p2o5

P underscore 2 O underscore 3
Explain Why is H2O2 is not the empirical formula of hydrogen peroxide?
An empirical formula is the lowest ratio of elements in a compound. So since H2O2 can be reduced to HO (H1O1), that is the empirical formula. The molecular formula is H2O2.
What is the empirical formula of the phosphorus selenide?
P4Se3
What is the empirical formula of the phosphorus bromide?
PBr5
What is the empirical formula for the compound X39Y13?
X3Y is the empirical formula
How do you know if a formula is an empirical formula?
An empirical formula has no data about the structure of a compound.
What does an empirical formula show?
the empirical formula of a compound tells you the proportions of the elements in the compound. with that information you can make some inferences about the identity of the compound. for example a compound with an empirical formula CH4 tells us that for every carbon atom there are four hydrogen atoms. this means that the compound is methane because no other hydrocarbon can have these roportions (try drawing the lewis structure for C2H8, which doesnt exist. you cant!)
The lowest whole number ratio of the elements in a compound is called the?
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
