Accuracy - Answer-Refers to a measurement giving the actual value for a sample with a limited deviation; example: determining the weight of a sample to be 1g plus or minus 0.001g Precision - Answer-Repeatability of a set of measurements, and getting very close values to each other. Test tubes - Answer-small tubes that allow a large number of samples to be arrayed in a rack for easy processing. Beakers - Answer-Wide-mouthed cylinders with a lip to allow pouring Erlenmeyer flasks - Ans...

PAG 2.2 Questions and Answers | Latest Version | 2024/2025 | Graded A+ How can you determine the molar mass of an acid? Weigh the container with H3X.nH2O, transfer the solid to a 250 cm3 beaker, and re-weigh the container. Dissolve the solid in 100 cm3 of distilled water and stir. Transfer the solution to a 250 cm3 volumetric flask, rinse the beaker, and add the rinsings to the flask. Fill the flask just below the mark, insert the stopper, and mix well. Transfer 25 cm3 of NaOH solution i...

if the p-value is greater than 0.1, we generally conclude the data are consistent with the null hypothesis - true what is the best way to characterize the random error present in a measurement? - take replicate measurements of your analytes and using the standard deviation and a t-table specify an error bar with a confidence limit statistical interference assesses whether an observed phenomenon in the data can reasonably be attributed to chance or not - true suppose we collecte...
