To determine the formula of a new substance one of the first steps is to find?
The chemical formula is determined by chemical analysis of the components.
What steps should be used to determine the empirical formula of a compound from its mass percent composition?
A) Convert each mass to grams. B) Divide each molar amount by the ...Top answer: B) Divide each molar amount by the smallest molar amount
What steps are used to convert an empirical formula into a molecular formula?
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 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
How do you determine the atomic weight percent of an element in a compound?
To determine the weight percent of the elements in a compound, you only need to two things: the formula of the compound and a periodic table. With that, just follow these three steps.1) Determine the molecular weight (or molar mass) of the compound. For instructions on how to do that, see the Related Questions links to the left.2) For each element in the compound, multiply the atomic weight of that element by the number of times it occurs in the compound. Do this for each element you want to know the weight percent for. See the example below for more about how to do this.3) For each element, take the answer you got in Step 2, and divide it by the number you got in Step 1, and then multiply by 100%. In other words, take the weight of each element in the compound, and divide by the total weight, and then multiply by 100 to make it a percent (instead of a fraction).--EXAMPLE: What is the percent by mass of carbon and hydrogen in C9H20?--ANSWER: First, according to Step 1, we must find the molecular weight of the compound. To do that we multiply the atomic weight of each element by the number of times it occurs in the compound:(9 * 12.011) + (20 * 1.008) = 128.259 grams per mole.Now, let's look at carbon (C). According to the formula, there are 9 carbons in the molecule. Multiplying them as in Step 2, we have:9 * 12.011 = 108.099Finally in Step 3, we take this and divide it by the total weight:108.099 ÷ 128.259 = 0.84281Then multiply by 100%:0.84281 * 100% = 84.281% carbon by mass in C9H20.Now we can do the same thing again, but for hydrogen (H):20 * 1.008 = 20.1620.16 ÷ 128.259 = 0.157180.15718 * 100% = 15.718% hydrogen by mass in C9H20.Finally, we can do a quick double check. Since the compound only has carbon and hydrogen in it, the two percents that we found better add up to 100%!84.281 + 15.718 = 99.999 .... which is just slightly off due to rounding errors, but that's close enough!

The chemical formula is determined by chemical analysis of the components.
The percentage composition of a polymer used for the non-stick surfaces of cooking utensils is 24 percent C and 76 percent F by mass Explain the steps in determining the empirical formula of the polym?
C = 24/12 = 2 F = 76/19 = 4 so the composition is C2F4 which is TetraFluoroEthylene and the polymer would be PTFE - TEFLON
What do you need to calculate the percent-age composition of a substance?
The molecular formula of the compound can be calculated from the composition of element in a compound. The next steps are involved in the calculation of percentage of every element in a compound.

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.
