Select the best answer for the following density related questions.                   1) If the weight of the reading were erroneously high, the calculated density would be:                         A) too high                  B) too low                   C) unaffected                   2) If the measured volumes were erroneously high, the calculated density would be:                         A) too high                  B) too low                   C) unaffected                  3) If the volume of the unknown solid was measured by displacement of sea water solution, instead                  of deionized water (DI water) displacement, the resulting density of the metal would be:                         A) too high                  B) too slow                 C) unaffected
