Can someone tell me where I am going wrong with these problems? I need it step by step please. Also, I asked this somewhere else, but both the answers that I got were wrong, so if your not sure, please don't answer. Thank you!
A concentrated HCl solution is 12.0 M. You have to make 300 ml of 0.600 M solution. How would you prepare it?
I worked it this way, which is the way the book tells us, but obviously get the wrong answer every time.
12.0 M x V1= 0.600 M x .300 L/ 12.0 M=
A concentrated solution of 15% w/v KOH solution is available. How would you prepare 20.0 ml of a 0.10% w/v KOH solution.
I worked this one (%1)V1=(%2)V2, by saying
(15%)V1=(.10%)(.200L)/ 15%
again the answer I get is wrong.
Can someone explain to me what I am doing wrong with these problems? Thanks so much!
