총 1장부터 22장까지의 솔루션이 있습니다. 기초과학인 일반화학 수업을 듣기 위한 솔루션입니다. For the above number expressed in scientific notation, n  6. The decimal place must be moved 6 places to the right to convert to nonscientific notation.
Since 0.000000621 is a number less than one, n is a negative integer. In this case, n  7.
Strategy: Lets express scientific notation as N  10n. When dividing numbers using scientific notation, divide the N parts of the numbers in the usual way. To come up with the correct exponent, n, we subtract the exponents.

(c) Subtraction using scientific notation.

1.25 (a) 145.75  (2.3  101)  145.75  0.23  1.4598  102
Divide the N parts of the numbers in the usual way.
Strategy: Lets express scientific notation as N  10n. When adding numbers using scientific notation, we must write each quantity with the same exponent, n. We can then add the N parts of the numbers, keeping the exponent, n, the same.

Since 802.6 is a number greater than one, n is a positive integer. In this case, n  2.

The usual practice is to express N as a number between 1 and 10. Since we must decrease N by a factor of 10 to express N between 1 and 10 (1.8), we must increase 10n by a factor of 10. The exponent, n, is increased by 1 from 3 to 2.
9.5  103

(d) (1.0  104)  (9.9  106)  9.9  1010
Let’s write 850,000 in such a way that n  5. This means to move the decimal point five places to the left.
850,000  8.5  105

3.256  105  0.00003256

Solution: Write each quantity with the same exponent, n.
 8.5  103
18.0  103  1.8  102

Solution: Make sure that all numbers are expressed in scientific notation.

6.53  5.75  1.14

Combining the above two steps:
1. Introduction

0.749  7.49  101

6.03  106  6,030,000
Subtract the exponents, n.

Solution: Write each quantity with the same exponent, n.

1.24 (a) Express 3.256  105 in nonscientific notation.

Solution: The decimal point must be moved seven places to give N, a number between 1 and 10. In this case,
Let’s write 0.0095 in such a way that n  3. We have decreased 10n by 103, so we must increase N by 103. Move the decimal point 3 places to the right.
