Chapter 1, Problem 1.4P

(a)

Interpretation Introduction

Interpretation:

The given quantity has to be expressed with abbreviations for units and prefixes.

Concept Introduction:

SI units refers to ‘International System of Units’ which have been used in the modern scientific calculations and metric system.

It constitutes units of measurement of seven basic parameters – length, mass, time, electricity, temperature, amount of substance and luminous intensity.

The units derived from the seven fundamental units that are stated above are termed as SI derived units.

The SI unit of measurement and derived SI units must be written as symbol in lowercase but unit named after a scientist must be written with first alphabet as uppercase.

Prefixes are the terms used to express smaller and larger quantities – in microscopic and macroscopic level.

Explanation of Solution

The quantity 1013 joules can be expressed as 100 fJ. fJ is femtoJoule and the prefix femto is equivalent to 1015 100 can be written as 102 and so 100 fJ is equivalent to 1013 joules as 102×1015J = 1013J. 1013 joules can also be written as 0.1 pJ. pJ is picoJoule and the prefix pico is equivalent to 1012 . Thus 0.1 pJ is equivalent to 1013 joules as 0.1×1012J = 101×1012J=1013J.

Explanation of Solution

The quantity 1010meters can be expressed as 0.1 nm. nm is nanometer and the prefix nano is equivalent to 109. 1010meters can also be expressed as 100 pm. pm is picometer and the prefix pico is equivalent to 1012. Therefore

1010meter = 0.1 ×109m = 0.1 nm                   = 102×1010102m                   = 100×1012m = 100 pm

Explanation of Solution

The quantity 48.3×1020moles can be expressed as 0.483 amol or 483 zmol. amol is attomole and zmol is zeptomole. the prefix atto is equivalent to 1018 and the prefix zepto is equivalent to 1021. Therefore

48.3×1020moles =483 ×1021 moles                         483 zmol

Also,

48.3×1020moles =0.483 ×1020×102 moles                         = 0.483 ×1018 moles = 0.483 amol
