## Problems of Percentage Yields

For those who do you know Steven Speilburg Directed ET, If you did not know that then YAY KNOWLEDGE, If you did then get started on these percentage problems, they are not going to do themselves you know.
* Just a couple notes before you get started,
Do not put the percentage or units within the Query box
During the problems, I, the writer, do not round and so even at the end of the problem when I do round that answer may be diffeent then yours, If you want to get an answer closest to mine do not round till the end.
For all others, round up or down depending on the chemical
Also Correct answers and step by step go throughs of the equation are on the next page
Chlorine has an atomic weight of 35.45, DO NOT ROUND
LASTLY, if you get a question right, the page simply refreshes. If you get a question wrong, a box pops up and will tell you, you are wrong, then refresh the page.
