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.

Introduction to chemistry

Chemistry is a branch of science that deals with the analysis of material and the substances that comprise it. It also manages the properties of these substances and their reactions to form new substances. It is basically centered on particles and atoms that make up components and mixtures. These chemical species will in general connect using bonds.
