Two students each measured the density of a quartz sample three times: Student A
Student B
1. 3.20 grams/mL 2.82 grams/mL
2.2.58 grams/mL 2.48 grams/mL
3. 2.10 grams/mL
2.59 grams/mL
mean 2.63 grams/mL
2.63 grams/mL
The density found in the Handbook of Chemistry and Physics for quartz is 2.65
grams/mL
