## Chemistry: Atoms First (2nd Edition)

a) First beaker: $33$ Second beaker: $30$ Third beaker: $32.7$ b) It is possible for all three beakers to contain the same amount of water. It was not reported as such because of the different precision of measurement in each beaker. c) The sum of all the volumes is 95.7. Since the second beaker has only 1 significant digit, the result also has only one. Therefore, the correct way to report the result is as $100$.
