How can the use of different balances in an experiment affect the results?

The choice indicating that using different balances may produce inconsistent mass results, leading to incorrect conclusions is correct because different balances can have varying levels of precision and accuracy depending on their calibration, type, and design. For instance, analytical balances are designed for high precision, often measuring to four decimal places, while a standard balance may only measure to two decimal places.

If an experiment relies on consistent mass measurements for calculations or comparisons, switching between different types of balances can introduce discrepancies. Variations in temperature, humidity, or even the placement of the sample on the balance can affect the readings. Therefore, rather than providing reliable and consistent results, using different balances can skew data and lead researchers to erroneous conclusions about the mass of the substances being measured.

This outcome highlights the importance of using the same balance throughout an experiment to maintain consistency and reliability in findings. Relying on one type of balance diminishes variability caused by measurement tools and helps ensure that the results are valid.
