Expressing the uncertainty of a standard solution

I have to standardize some standards solutions and I am wondering about the certain decimals of the title.
For example. I have to standardize astandard solution of
0.01 N Silver Nitrate. Which is the right expression of title: 0.010, 0.0100 or 0.01000
Which decimal position should include the uncetrainty?

First of two simultaneous responses --

0.01N means that it is between 0.005 and 0.014 in reality.
0.010N means that it is between 0.095 and 0.014 in reality. The latter is a normal level of "standards" in a plating lab.
0.0100 is unrealistic for most labs.

Second of two simultaneous responses --

That depends entirely on exactly how you standardize the solution, i.e., measurement method precision and accuracy.
