Chapter 1, Problem 1.73QP

Interpretation Introduction

Interpretation:

It should be calculated the mass of the following cases.(a),(b),&(c)

Concept Introduction:

Volume is the ratio of mass to density and its SI unit is ${\text{m}}^{\text{3}}$.

$Volume=\frac{Mass}{Density}$

The volume of the sphere is calculated by using the

$\text{V=}\frac{\text{4}}{\text{3}}{\text{πr}}^{\text{3}}$

By using the density equation we can find the mass,

$\begin{array}{l}\text{d=}\frac{\text{m}}{\text{V}}\\ \text{or}\\ \text{m=dV}\end{array}$
