4.3 × 10^{−6} is between which two numbers?

a. 1 × 10^{−7} and 1 × 10^{−8}

b. 1 × 10^{−6} and 1 × 10^{−7}

Scientific notation can be used to express very large or very small numbers more easily. For example,

299800000 = 2.998 × 10^{8}

0.00000509 = 5.09 × 10^{− 6}

In Mastering Chemistry, you may enter answers in scientific notation in the following format:

2.998*10^{8}

5.09*10^{-6}
