The actual weight of the beaker is 82 grams and the measured weight is 78 grams.
The difference between the two weights is 82 - 78 = 4 grams.
To find the percent error, we divide the difference by the actual weight and multiply by 100:
Percent error = (4 grams / 82 grams) x 100 = 4.88%
Rounded to the nearest percent, the approximate percent error is 5%.
Therefore, the answer is B) 5%.
