Chapter 3.4, Problem 3TY

Interpretation Introduction

Interpretation:

The more precise volumetric dilution than using a $1000\text{μL}$ micropipette and a $10\text{ mL}$ volumetric flask has to be described.

The relative uncertainty in the dilution has to be given.

Concept Introduction:

Uncertainty:

Uncertainty means state of not certain in predicting a value.  In a measured value, the last digit will have associated uncertainty. Uncertainty has two values, absolute uncertainty and relative uncertainty.

Absolute uncertainty:

Expressed the marginal value associated with a measurement

Relative uncertainty:

Compares the size of absolute uncertainty with the size of its associated measurement

$\text{Relative uncertainty = }\frac{\text{absolute uncertainty}}{\text{magnitude of measurement}}$
