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.
