Example of an acceptable entry: 2.347E-6  (Note: No spaces!)  
1. What was your assigned concentration?  Include  the E-6 part AND units (mol/L). *
Example: 3.82E-6 mol/L
2. (9 pt) What was your concentration according to the spectrometer (enter your best result if you did it more than once)? *
Enter your answer including the E-06 mol/L!  This is where your accuracy is graded for this experiment.
3. (2 pt) What is the percent error between the assigned concentration and your actual concentration? Write the word "percent" after your answer -- do not use the "%" sign.  (Long boring story.)
Units are percent.  Report your answer to the 0.1 place.
