question 8 of 24
look at the table below. rewrite the mass for the third object in scientific notation.

object	mass (g)
2	35.090
3	0.0000008
4	6,084,000
5	700.00

a. 8.0 x 10^-8
b. 8.0 x 10^-6
c. 8.0 x 10^-5
d. 8.0 x 10^-7

Explanation:

Step1: Recall scientific - notation form

Scientific notation is $a\times10^{n}$, where $1\leqslant|a|\lt10$ and $n$ is an integer.

Step2: Move the decimal point

For the number $0.0000008$, move the decimal point 7 places to the right to get a number between 1 and 10. So, $a = 8.0$ and since we moved the decimal point 7 places to the right, $n=-7$.

Answer:

D. $8.0\times 10^{-7}$
