(b) Express 802.6 in scientific notation.
1.23 (a) 15,200 (b) 0.0000000778
0.0095 9.5 103
Divide the N parts of the numbers in the usual way.
[해답] 일반화학 7판 해답(사이플러스) 입니다. Combining the above two steps:
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) Express 0.000000621 in scientific notation.
Solution: Make sure that all numbers are expressed in scientific notation.
8.5 103
0.749 7.49 101
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.

N 8.026
Solution: The decimal point must be moved two places to give N, a number between 1 and 10. In this case,
3.256 105 0.00003256
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.

(c) Subtraction using scientific notation.
1.24 (a) Express 3.256 105 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.
6.53 5.75 1.14
For the above number expressed in scientific notation, n 5. To convert to nonscientific notation, the decimal point must be moved 5 places to the left.
Solution: Write each quantity with the same exponent, n.
0.000000621 6.21 107
1.25 (a) 145.75 (2.3 101) 145.75 0.23 1.4598 102
Combining the above two steps:
Since 802.6 is a number greater than one, n is a positive integer. In this case, n 2.
(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.
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.
Add the N parts of the numbers, keeping the exponent, n, the same.
