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

To predict the theoretical yield we would have to know the amount we of product we actually produced in a reaction, and the amount that should have been produced based on calculations involving the balanced equation for the reaction.

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 :)

Mgo2 is the oxidation state of manganese oxide

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
