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

Answer 1

To find the weight of all the ants in the world, we can simply multiply the weight of one ant by the total number of ants.

Weight of one ant = 3×10^-6 kg
Total number of ants = 1×10^16

Weight of all the ants = (3×10^-6 kg) * (1×10^16)
= 3×1 * 10^-6 * 10^16
= 3×10^10 kg

So, the approximate weight in kilograms of all the ants in the world is 3×10^10 kg in scientific notation.
