Converting to Scientific Notation Examples!

Scientific Notation ( An introduction )

Use scientific notation to express each quantity with only base
units (no prefix multipliers).
a. 4.5 ns
b. 18 fs
c. 128 pm
d. 35 mm

The diameter of the Earth at the equator is 7926.381 mi.
(b) Express the answers in scientific notation.

Express the following measurements in scientific notation.
(a) 453.32 mg

Convert the following expressions into exponential notation: 
(b) 2.5 femtoseconds (fs)

Scientific Notation: Introduction

Scientific Notation Example 1

Convert the following measurements from scientific notation to standard notation.
(a) 3.221 * 10-3 mm 
(b) 8.940 * 105 m 
(c) 1.350 82 * 10-12 m3 
(d) 6.4100 * 102 km

(b) The circumference of
Earth through the poles is 40,008 km. Round this number to
four significant figures and express it in standard exponential
notation.

SI Units

The International System of Units (SI) is related to the metric system and is based on seven base units.

Physical & Chemical Changes

A physical change involves a change in the phases of matter, whereas a chemical change involves a change in chemical bonds.&nbsp;

Physical Properties

Physical Properties are measurable properties that describe the state of chemical compounds.&nbsp;

Significant Figures: In Calculations

Significant Figures are often involved in chemical calculations.&nbsp;

Scientific Notation is used to turn small or large inconvenient numbers into manageable ones.&nbsp;

Density of Non-Geometric Objects

The density of non-geometric objects can be determined using water displacement.&nbsp;

Density

Density represents the mass of an object or compound within a given volume.&nbsp;

Significant Figures: Precision in Measurements

Significant Figures are used to discuss the level of precision in any measurement.&nbsp;

Intensive vs. Extensive Properties

Intensive Properties are independent and Extensive Properties are dependent on the size or amount of substance present

Density of Geometric Objects

The density of geometric objects generally includes spheres, cubes and cylinders.&nbsp;

Significant Figures

Significant Figures are used to determine some level of accuracy within our recorded measurements.&nbsp;

Dimensional Analysis

We use dimensional analysis&nbsp;as a fail proof process to convert from one unit to another.

Chemical Properties

Chemical Properties are observed during chemical reactions.&nbsp;

Temperature

Temperature is a measure of the amount of average kinetic energy of the atoms in a compound.

Metric Prefixes

Metric Prefixes are “labels” that can be placed in front of base units.&nbsp;

Conversion Factors

Conversion Factors represent ratios or fractions composed of different units.&nbsp;

Classification of Matter

Chemistry is the study of matter and the changes it undergoes, with the atom being its basic functional unit.&nbsp;
