Relative error to absolute error?

Question

I'm asked to use the relative error to find the absolute error of [Na₂S₂O₃]

I've calculated these amounts in previous questions:
[Na2S2O3] = 0.01001M
Relative error: 0.3%

is there other information I should have for this calculation?

Is it 0.3% of the concentration, 0.01001/0.003 = ±0.00003

Answer 1

According to some definitions, the absolute value is the difference between the measured value and the actual value.  It is always positive in sign.

The relative error is the absolute value (defined in the above sentence) divided by the actual value.

 

Can you take it from there Haley?
