An industrial chemist used a volumetric flask to prepare 250.0 cm3250.0\text{ cm}^3250.0 cm3 of a standard sodium hydroxide solution.
The volumetric flask is calibrated to 250.0±0.15 cm3250.0 \pm 0.15\text{ cm}^3250.0±0.15 cm3.
Calculate the percentage uncertainty in the volume measured using this volumetric flask.
Use the equation:
percentage uncertainty=uncertaintyvolume measured×100\text{percentage uncertainty} = \frac{\text{uncertainty}}{\text{volume measured}} \times 100percentage uncertainty=volume measureduncertainty×100
