- Theoretical
Yield :
- The maximum amount of product that can, according to chemical reactions, be
obtained from a known amount of reactants. Cannot reach theoretical yield in
reality, instead find percent yield.

Analysis :
- A method for solving conversion type problems
- a. Understand the question
- b. Understand what is given and units involved
- c. Figure out which conversion factors you need
- d. Decide how to use the factors
- e. Keep the units as a check for your work

- Accuracy :
The measure of agreement between your average of measurements and the correct
value
- Precision
: The closeness of agreement among repeated measurements.

Deviation :
- Indicates confidence limits for analyzed data, which gives you an idea of
how widely spread out your data is and you can recognize outlying values.
- Calculations:
- Determine the mean, m.
- Subtract the mean from each measured data item, d.
- Square each difference, d².
- Find the average of the squared terms in step 3 by dividing by (n-1), n is
the number of measurements taken.
- Calculate the square root of the average found in step 4.
