10. In Lesson 10A, Question 3, the question should refer to problems 2A and 2d.
11. In Lesson 11D, Question 5, the mass should be 6.6 x 10-24 g/atom in the question and answer.
12. In Lesson 11D, Question 3, the question should be "per cubic inch."
In versions prior to March 16, 2009:
13. In Lesson 17B, Practice Question 5, the answer unit should be molecules, not molecules/L.

In Lesson 22A, in the Q on Engineering Notation, the A should be 52.7 pm, not 527 pm.
In versions between August 1 2009 and September 8, 2009:
15. In Lesson 1A, negative values were added to the examples, but the rules were not changed to accomodate this.. For the rules of moving the sign to work for negative values, the rule "the sign is independent of the significand and exponential term, and the sign never changes" must be added for values that are negative.
Between Nov 13 and Nov 18, 2009,
16. In Lesson 10F on limiting reactants, the sample calculation was wrong. Check the newer version.
Between September 9 and Dec 5, 2009,
