Although sometimes we use qualitative (verbal) words to describe the accuracy (such as good accuracy and bad accuracy), a quantitative (numerical) measure is more useful when comparing 1.4275 or 4 (1.43 1.43 1.43 1.42)
WebAug 27, 2024 · What is the most precise glassware in chemistry? August 27, 2024 by Alexander Johnson The volumetric flask is the most accurate, but it only measures 1 volume—in this case, 100mL. If you need to measure other volumes besides those on … WebThe standard deviation is related to the precision of the measurement. If a pipet is supposed to dispense 10 mL and it actually dispenses 15, 16, and 15 mL then it has high precision (because the numbers are close.) Its accuracy is way off because the average of 15.3 mL is half of an order of magnitude different than 10.
WebThis involves using glassware that can contain or deliver a volume known to a few hundredths of a milliliter, or about 0.01 mL. One can then report quantities greater than 10 mL to four significant figures. Glassware designed for this level of accuracy and precision is expensive, and requires some care and skill to give best results.
