The weight of an ant averages about 3 times 10^-6kg. There are about 1 times 10^16 ants in the world. What is the approximate weight in kilograms of all ants in the world? Write the answer in scientific notation.

Answer 1

To find the total weight of all ants in the world, we multiply the average weight of an ant by the total number of ants:

(3 x 10^-6 kg/ant) * (1 x 10^16 ants) = 3 x 10^10 kg

Therefore, the approximate weight of all ants in the world is 3 x 10^10 kilograms in scientific notation.
