Chemistry · Some Basic Concepts of Chemistry

Three students performed an experiment to determine the mass of a chemical sample whose true value is 2.00 g. Their recorded data are as follows: - Student A: 1.95 g, 1.93 g - Student B: 1.94 g, 2.05 g - Student C: 2.01 g, 1.99 g Afterwards, a titration was performed, giving readings of 11.4 mL, 11.5 mL, and 11.7 mL, while the true value was 11.9 mL. Based on the data above, which student's results are both precise and accurate, and how are the titration readings characterized?
