    Precision and accuracy of a solution

    so let's assume that final result is true , so it would be 8*10^-5 ±1/40 and so for all resulting solutions and that by using Δy/y correct me if I'm wrong thanks and sorry for my stubbornness

    Precision and accuracy of a solution

    so so what you say is that no mater how many dilution we do the precision stays the same and it depends on the solution we're using.so it means ±0.01 for all diluted solutions we made,right?

    Precision and accuracy of a solution

    Homework Statement so let's say that we have a solution S=0.4±0.01/250ml i want to do a dilution so i pick 5ml and pour it into 100ml beaker how should i calculate precision of the solution (mathematically or with some other equations)? Homework Equations so basically we have F=5*S/100 The...
