Was the concentration of 6.45 x 10^-4 M correct? Just so I know I understand the concept?
So I am not sure where things are going wrong?
That's the equation I used! I found moles to be 3.22 x 10^-4 mol and concentration to be 6.45 x 10^-4 M. I found the rate to be 8.60 x 10^-7 M/s, but the answer in my textbook is 7.55 x 10^-7 M/s
Please show steps! Thanks!
