Chapter 1, Problem 92AP

Interpretation Introduction

Interpretation:

The mass of osmium in pounds and in kilograms are to be calculated.

Concept introduction:

Density is known as mass per unit volume.

$d=\frac{m}{v}$ Here, $d$ is the density, $m$ is the mass, and $v$ is the volume.

Density estimates the amount of matter present in an object with its volume.

The units of mass are grams, kilograms, pounds etc.

The volume of a sphere is given as follows:

$v=\frac{4}{3}\text{π}{r}^3$

$\text{1 kg = 1000 g}$, to convert gram to kilogram, the conversion factor is $\frac{\text{1 kg}}{\text{1000 g}}$.

$1\text{ kg}=2.205\text{ lbs}$, to convert kg to lb, the conversion factor is $\frac{2.205\text{ lb}}{1\text{ kg}}$.
