An instructor gives a student a 103.1 g sample of a compound. A student takes this sample and using'one of the laboratory balances measures the sample 4 times. He got the following results: 105.1 g 104.9 g 105.2 g 105.1 g Based on these results, how would the student's measurements best be characteriz ed? Assume that the sample's mass is actually 103.1 g. a) The measurements are both accurate and precise. b) The measurements are accurate but not precise. O c) The measurements are precise, but not accurate. d) The measurements are neither accurate nor precise.

Transcribed Image Text:An instructor gives a student a 103.1 g sample of a compound. A student takes this sample and using'one of the
laboratory balances measures the sample 4 times. He got the following results:
105.1 g
104.9 g
105.2 g
105.1 g
Based on these results, how would the student's measurements best be characteriz ed? Assume that the
sample's mass is actually 103.1 g.
a) The measurements are both accurate and precise.
b) The measurements are accurate but not precise.
O c) The measurements are precise, but not accurate.
d) The measurements are neither accurate nor precise.
