Q3. Why does the percent-error equation use the absolute value of the error? Learning Activity 1For this this topic, I want you to read Lesson 2.1 in your Textbook General Chemistry 1 by Aristea V.Bayquen and Gardee T. Peña, page 29.Student Density and Error Data(Unknown was sucrose; density=1.59g/cm3Student AStudent BStudent CError (g/cm) DensityError (g/cm3)Error (g/cm3)Density1.54 g/cm1.60 g/cm?1.57 g/cm31.57 g/cm?1.40 g/cm31.68 g/cm?1.45 g/cm1.51 g/cm?Density1.70 g/cm31.69 g/cm1.71 g/cm1.70 g/cm3Trial 1Trial 2Trial 3AverageConsider the data in the table. Students were asked to find the density of an unknown whitepowder. Each student measured the volume and mass of three separate samples. They reportedcalculated densities for each trial and an average of the three calculations. The powder, sucrose(table sugar), has a density of 1.59 g/cm².Q1. Which student collected the most accurate data? Q2.Who collected the most precise data?Using the table above as reference, analyze and provide answers to the given questions.The density values reported in the table above are experimental values, which means theyare measured during an experiment. The known density of sucrose is an accepted value, which is avalue considered true. To evaluate the accuracy of experimental data, you can compare how closethe experimental value is to the accepted value. Error is defined as the difference between anexperimental value and an accepted value. Compute for the value of errors in the table given.

Compute for the value of errors in the table given.Error EquationError = experimental value – accepted valueThe error is associated with an experimental value is the difference between the experimental value and theoccepted value.Scientist often want to know what percent of the accepted value an error represents. Percenterror express error as a percentage of the accepted value.Percent Error EquationPercent Error=lerror|accepted valuex 100The percent error of an experimental value equals the absolute value of its error divided by the accepted value,multiplied by 100.Q3. Why does the percent-error equation use the absolute value of the error?
