How do I calculate the overall confidence limit and the overall relative confidence limit for the percent chloride?
I've found the percent mass of chloride in the unknown to be 60.03 % and the formula we were given uses the mean but I have no mean in this case so I am confused

• Chemistry -

You didn't run three or more trials and the average was 60.03%?
If you were simply given (or ran only one sample) of 60.03% I would use that as the mean. But with just one result the C.L won't be all that great.

So should I use the decimal form 0.6003? Or the 60.03%?
