Answer: D. 6.5 g


Explanation:

From the given table , weight of sample 1 = 1.25050 g

Weight of sample 2 = 2.50055 g

Weight of sample 1 = 2.74099 g

The total weight of all the 3 samples=
1.25050\ g+2.50055\ g+2.74099\ g

Therefore, the total weight of all the 3 samples=
6.49204\ g

Since,
6.49204\approx6.5

Thus, the estimated total weight of all 3 samples= 6.5 g
