Hi, I made a few solutions and I have to determine the concentration error. The calculations should be based on volume of flasks. I prepared solutions in 100ml flasks, concentrations: 0.1M, 0.09M, 0.08M, 0.07M, 0.06M. I have no idea how i can count this.

Each flask will have an error rating, normally printed on the side. You can calculate it from that.

so i should add this error rating to volume (100ml) and then count the concentration??

Calculate, not count English differs from Polish in this aspect.

That will give you highest theoretical concentration, not the error.
