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

What is the tolerance of a balance?

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.

Since no mass reading was given, let's make two assumptions about mass reading.

Mass reading    Assumptions

1                           6.521 g

2                           4.23 g

  • The balance used for the 6.521 g mass reading is a balance with ±0.001 g tolerance.
  • The balance used for the 4.23 g mass reading is a balance with ±0.01 g tolerance.
