Hi folks,
Lots of fun math today. Today we got into the wonderful world of the mole and stoichiometry. This is one of the tougher mathematical concepts of the year but one of the most important as well. Homework this week will be to do quite a bit more work with these problems. The answers are included so be sure to take your time and discover how to do them. Next week's quiz will be heavy on these so be prepared. Be sure to study the quiz you got back this week. Many folks had some issues on it and those problems will return to haunt you. Beware! :)
Homework due 1/31 is to do problems 5-8 in the enclosed .pdf.
Also, here's a couple of percent composition problems to practice with as well. Email me if you would like the answers to these.
1. What is the percent composition of each element in K2CrO4?
2. What is the percent composition of each element in C3H8?
