A balance is best used to measure a sample’s _______. a. volume b. length c. mass d. size
slamgirl [31]

A balance is best used to measure a sample's mass.

Answer: C

Explanation:

Weighing balance refers to a measuring instrument which is used to measure the mass of the sample.

It has two pans. On one pan, the material to be weighed is placed, with adequate known loads on the other one to such an extent that the shaft will be in balance.

The distinction between the zero perusing and the perusing with the dish stacked demonstrates the contrast between burdens in scale divisions.

Such an instant weighing needs the arms be of equivalent length.
