Steps

What are the steps for determining the percent yield if you are given the mass of the two reactants?

First you go and find your actual yield which is usually given to you when you want to find your percent yield. Then you work out the proplem to find the mass of the product and that will be you theoretical yield. Then you take the actual yield and divide it by your theoretical yield and times it by 100 then you get your percent yield.

You have to find the actual yield of the product. than you have to figure out the mass of the product and than you get your theoretical yield from that. After you find your theorectical yield than you divide them and times by 100 and thats how you get you percent yield

first find the actual yeild, and find the molar mass. Divide the theoretical yeild and take it times 100 and thats how you find percent yeild.

If you are given the masses then you have to convert them to moles. Once you get them to moles you have to find which element is your limiting and which one is your reactant. Then you divide your actual yield by your theoretical yield.

First you find your actual yeild and your theoretical yeild. Thats a good thing to figure out because you are going to need them in order to do the next step. Divide your actual by your theoretical and then multiply by 100. That's how you do it.

The first step is to create a balenced chemical equasion. then find the teoretical yeald. now find the number of moles you have.

First find your actual yield of the product. If the given numbers are in the grams, you have to switch them to moles. Then you figure out the molar mass, by the periodic table. Then you divide the theoretical yeild and take it times 100 to get the percent yeild.

First you find the actual yield. This is usually given. Then you find the theoretical yield. Then you put atcual over theoretical. Then take it times 100 to get your percent.

The first thing you have to do is find the percent yield. Then you have to find the mass and that will give the theoretical yield. Next take the actual yield divided by the theoretical yield. After that multiply by 100 and that will give you your percent yield.

To find the percet yeild, you need to have actual over theoreical. You need to set up equations with the boxes. You also need to times it by 100 to get the correct answer.

Find you go and find actual yield which is usually given to you. Then you divide it by the theoretical yield. Then Times it by 100 to get your percent yeild

Reeber said...

First thing is you have to get a balanced equation. Then you have to find the actual yield. Then you can divide it by the theoretical yield.

First you must convert the masses to moles. Then, figure out which is your limiting and which is your excess. Next, find your theoretical yeild and actual yeild. Last, divide your actual yield by your theoretical yield to get the percent yeild.

bertsch said...

First you find the theoretical and actual yield. Then put actual over the theoretical. Then you multiply by 100.

tara said...

You need to find the actual yield first of your compound. THen you have to go through and find your theoretical yield. Divide you actual yield over your theoretical yield and take it times 100.

Find the theoretical yield for the two reactants by using the charts. Then you divide the actual yield by the theoreitical yield. This will give you the percent yield.

jacob ochsner said...

Find the theoretical yield. Then divide your actual by your theoretical. Then take it times 100.

Mindy said...

First, you have to find your actual yield. But it should be given to you in the equation. Then you have to find the mass of the product which is your theoretical yield. Next, you have to divide the actual yield by the theoretical yield. When you find that total, multiply it by 100. The number that you get is called your percent yield.

You have to convert your mass to moles first. Then to find the theoretical yeild you divide them and then you would times them by 100. When you get your decimal then you move it over two spots and that is your percent.
