A technician used a graduated syringe to measure 40.0 cm340.0\text{ cm}^340.0 cm3 of an anhydrous solvent.
The syringe is calibrated to 40.0±0.12 cm340.0 \pm 0.12\text{ cm}^340.0±0.12 cm3.
Calculate the percentage uncertainty in the volume measured using this syringe.
Use the equation:
percentage uncertainty=uncertaintyvolume measured×100 \text{percentage uncertainty} = \frac{\text{uncertainty}}{\text{volume measured}} \times 100 percentage uncertainty=volume measureduncertainty×100
