Homework Help: Chemistry

Posted by Steve on Tuesday, January 23, 2007 at 4:32pm.

I have the following equation:

0.5 ug/L x 1g/10^-6ug x 1 mol/27 g

I can't divide by 10^-6...how do I rearrange the equation?

What is the problem with dividing by 10^-6? Anyway, you can multiply by 10^6 instead.

I end up with an error message when I divide 1/10^-6...
so, you are saying just invert and multiply by 10^6

right. 1/10^-6 = 10^6/1.
Isn't 1/0.1 = 1/10^-1 = 10^1/1 = 10?

YES...I see.
Thanks
