Question

Identify which balance was used to make each mass reading. 0.90 g Choose... 1.230 g Choose... 5.43 g Choose... 4.0000 g Choose... 6.539 g Choose...

Answer 1

The balance that can be used to measure a mass reading of 0.90 g will be a balance with ±0.01 g tolerance.

The mass reading       balance used for measurement

1.230 g                      ±0.001 g tolerance

5.43g                         ±0.01 g tolerance

4.0000g                    ±0.0001 g tolerance

6.539g                       ±0.001 g tolerance

What is the tolerance of a balance?

The tolerance of a balance is the number of decimal place values shown on the balance and it is the permissible limitations measured in grams, that a balance can tolerate.

• Hence, depending on the decimal place value behind a mass reading will determine the balance used for measurement.

From the given parameters:

The mass reading       balance used for measurement

0.90 g                        ±0.01 g tolerance

1.230 g                      ±0.001 g tolerance

5.43g                         ±0.01 g tolerance

4.0000g                    ±0.0001 g tolerance

6.539g                       ±0.001 g tolerance
