What is the empirical formula of an oxide of phosphorus that contains 43.6% phosphorus and 56.4% oxygen?

What is the empirical formula for a compound that is 43.6% phosphorus and 56.4% oxygen? 100 g of the compound contains 43.6 g phosphorus and 56.4 g of oxygen. The ratio of atoms of P and O, P : O = 43.6 / 31 : 56.4/16 = 1.4 : 3.5 = 2 : 5 So, the empirical formula of the compound is P2O5. Hope this helps.…

What are the steps to calculating an empirical formula?

Step 1: Determine the masses. Step 2: Determine the number of moles by dividing the grams by the atomic mass. Step 3: Divide the number of moles of each element by the smallest number of moles. Step 4: Convert numbers to whole numbers.

How do you find empirical and molecular formulas?

STEP 1: Calculate the molar mass of the empirical formula. STEP 2: Divide the given molecular molar mass by the molar mass calculated for the empirical formula. STEP 3: Multiply each subscript by the whole number that resulted from step 2. This is now the molecular formula.

What is empirical formula in mathematics?

Empirical equations are mathematical equations whose free parameters we have to specify by a given set of experimental data about a particular state to obtain formulas for predicting other data about this state.

How chrysene is formed?

Chrysene (CAS-218-01-9) is a polycyclic aromatic hydrocarbon (PAH) and one of the natural constituents in coal tar. It is produced as smoke during incomplete combustion of coal, gasoline, garbage, animal, and plant materials.

Is chrysene a PAH?

Chrysene is a polycyclic aromatic hydrocarbon (PAH). PAHs are a group of organic compounds that contain two or more benzene rings in their structure. There are more than 100 different PAHs that generally occur as complex mixtures (example, combustion by-products such as soot).

How do you find the empirical formula from the whole number?

In order to find a whole-number ratio, divide the moles of each element by whichever of the moles from step 2 is the smallest. If all the moles at this point are whole numbers (or very close), the empirical formula can be written with the moles as the subscript of each element.

What does the empirical formula show?

Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other.
