By determining the molecular mass, then dividing the molecular mass by the formula mass of the empirical formula to determine by what integer the subscripts in the empirical formula must be multiplied to produce the molecular formula with the experimentally determined molecular mass.

What are the steps determining the empirical formula of the polymer?
To determine the empirical formula of a polymer, first, identify the elemental composition by analyzing the polymer's molecular formula or by conducting elemental analysis to find the amounts of each element present. Next, convert these quantities into moles by dividing each element's mass by its atomic weight. Then, simplify the mole ratios to the smallest whole numbers to derive the empirical formula. Lastly, ensure that the empirical formula reflects the simplest ratio of the elements in the polymer.
What are the steps in writing a molecular compound?
First U have to write the symbols of elements that form the compound, forexample if we want to write the chemical formula of magnesium chloride:1. Mg Cl2. we have to write the valence of each element below itMg Cl2 1then, we switch the valences of each oneso, the chemical formula is going to be:MgCl2
What is Lab report for determination of the formula unit in a compound?
A lab report for the determination of the formula unit in a compound typically outlines the experimental procedure used to identify the empirical or molecular formula of the compound. It includes sections such as the introduction, where the purpose and significance of the experiment are discussed; the methodology, detailing the materials and steps taken; results, which present the data collected; and a conclusion that interprets the findings and confirms the formula unit. The report may also include calculations, such as molar mass and percent composition, to support the determined formula.

How can one determine the molecular formula from the given molar mass and percent composition?
To determine the molecular formula from the given molar mass and percent composition, you can follow these steps: Convert the percent composition to grams for each element present in the compound. Calculate the number of moles of each element using the molar mass and the grams of each element. Divide the moles of each element by the smallest number of moles to get the mole ratio. Use the mole ratio to determine the empirical formula. Calculate the empirical formula mass and compare it to the given molar mass to find the multiplier needed to get the molecular formula.
How do you find the molecular and empirical formulas?
There is no easy answer to this question. First, it depends what information you have to start with. Do you have the name? Do you know what elements are found in the substance?If you are given the name of the molecule, you can often find the molecular structure of that compound by simply using the Google search engine online and searching for the name. It is often give you the answer! There are certain compounds that you should be familiar with also. Also, there is a set of official rules that determine the name of a specific compound, so that if you have the formula, you can name it correctly, and if you have the name, you can determine the formula. Unfortunately, many chemicals also have common names that do not follow these rules, and you just have to memorize those, or look them up with Google.See the Related Questions and Web Links to the left for some information about how compounds are named and how to go from a formula to a name and vice versa.
