Question

3. A student weighed an unknown mass directly on an electronic balance of intermediate sensitivity, and got a result of 28.774 g. The student then realized a mistake had been made, and weighed the same unknown by difference on the same balance with the following results:

Mass of beaker plus unknown = 59.121 g.
Mass of empty beaker = 30.346 g.

When the sensitivity of the balance is taken into account, the two values obtained for the unknown mass are considered to be:
a. Different
b. The Same
Explain your answer.
