Error of concentration
« on: June 07, 2019, 05:12:46 PM »
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.
