Chapter 2, Problem 2.7P
Interpretation Introduction

Interpretation:

The buoyancy correction equal to 1, when density of an object is (8.0 g/mL) should be explained.

Concept introduction:

Buoyancy Correction:

The weight of the object in air is less then weight of the object in vacuum because of buoyancy, this weight variation is corrected using Buoyancy equation it is,

m=m'(1-dadw)(1-dad)

Where,

m is mass of object in vacuum.

m' is mass of object in air (read on a balance).

da is the density of air (0.001 2 g/mL near I bar and 25°C) .

dw is the density of calibration weights (8.0 g/mL) .

d is the density of the object being weighed.
