Question 12 of 30 Map University Science Books General Chemistry 4th Edition McQuarrie Rock Gallogly presented by Sapling Learning Several of students are attempting to determine the density of a lead weight by various methods. Their data is shown here Group 1 Group 2 Group 3 11.5 11.5 10.9 Trial 1 Measured Densities Trial 2 11.3 11.4 11.33 Trial 3 11.1 4 11.4 (g/mL) 11.1 Average 11.3 11.4 11.1 Density A handbook lists the density of lead as 11.3 g/mL. Which group was most accurate? Which group was most precise? O Group 1 O Group 1 O Group 2 O Group 2 O Group 3 O Group 3 Previous Check Answer Next Exit HintExplanation / Answer
Hi,
Group 1 is more precise since they got the same average value as listed in the handbook.
And group 2 is more accurate since the values they obtained in each trial are close to previous values.
Thank you
