What is the theoretical yield of something if 20g are formed with a 10% yield

For instance, suppose we made water from hydrogen and oxygen.  Starting with 2 moles of hydrogen and 1 mole of oxygen we should produce 2 moles of water (or 36 gram).  But suppose we actually ran the reaction in the lab and collected only 34g of water.

The percent yield would be 34g / 36g   x 100 =94.4%

So, if I'm reading your question correctly, 20g is the experimental yield and 10% is the percent yield.

Plugging in gives us                               10/100 =  20/x

The theoretical yield must be 200g.

I HOPE THAT HELP MY FRIEND :)

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
