Unformatted text preview: represents how many zeroes there are between the number and the decimal place: 0.1 = 1 x 10-1 0.01 = 1 x 10-2 0.001 = 1 x 10-3 As one can imagine, when expressing extremely large numbers, this method is most helpful. For instance, take the number 602,200,000,000,000,000,000,000. Using scientific notation, this number can be expressed as 6.022 x 10 2 3 , which is obviously much more convenient. Many, many numbers in chemistry, physics, and other sciences will appear in the scientific notation form. It pays to understand it. As we shall see in the next section, scientific notation also is generally more compliant with the rules of significant figures....
