The balance that can be used to measure a mass reading of 6.521 g will be a balance with ±0.001 g tolerance.

The tolerance of a balance is the number of decimal place values displayed on the balance and it is the acceptable measurement limitations (in grams) that a balance can tolerate.
- As such, depending on the decimal place value behind a mass reading will determine the balance used for measurement.
