Question

A chemistry student is given the task of analyzing three unknown samples. Her data is listed in Data Table 1. Use Data Table 1 to answer the questions below. Data Table 1 Trial Sample

A Sample B Sample C Mass (in grams) Volume (in mL) Mass (in grams) Volume (in mL) Mass (in grams) Volume (in mL) Trial 1 80.72 10.01 95.41 10.72 72.28 10.00 Trial 2 80.64 10.00 92.33 10.51 72.32 9.99 Trial 3 80.91 10.05 93.78 10.62 72.34 9.95 Average 80.76 10.02 93.84 10.62 72.30 9.98 Compare the data collected for each trial and each sample in Data Table 1.

Which sample(s) did the student measure precisely? Explain your answer.

Answer 1

The student’s measurements for Samples A and C are very precise. The data for these two samples is consistent.

That is the sample response if you wanna be precise with it.
