Use scientific notation to solve the problem.
-Assume that the volume of the earth is $5 \times 1014$ cubic meters and the volume of a bacterium is $2.5 \times$ $10 - 16$ cubic meters. If the earth could be filled with bacteria, how many would it contain?
A) $2.0 \times 10 ^ { 30 }$ bacteria
B) $5.0 \times 10 ^ { - 31 }$ bacteria
C) $2.0 \times 10 - 30$ bacteria
D) $5.0 \times 10 ^ { 31 }$ bacteria

Question

Quizplus · Accepted Answer

To find the number of bacteria that can fill the Earth, divide the volume of the Earth by the volume of a bacterium: $ \frac{5 \times 10^{14}}{2.5 \times 10^{-16}} = 2.0 \times 10^{30} $ bacteria.
