Answer
The weight of the beaker should be recorded as 15.00 g.
Solution
- The balance has an accuracy of
grams, meaning the measurement uncertainty is in the hundredths place. - To correctly represent the uncertainty, the recorded value should have digits up to the hundredths place.
- The beaker’s weight is given as 15 grams, so with the uncertainty considered, it should be written as
grams.
Thus, the correct representation is

The weight of the beaker should be recorded as 15.00 g. This is because the balance has an accuracy of
In scientific reporting, significant figures are key in conveying the certainty of a measurement. Using 15.00 g reflects that the weight is known to two decimal places, affirming both its precision and the instrument’s limits. This allows for clearer communication in experiments and data analysis.
