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.
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.
To find the approximate weight of all the ants in the world, you can 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 ants
Weight of all ants = (Weight of one ant) × (Total number of ants)
Weight of all ants = (3 × 10^-6 kg) × (1 × 10^16 ants)
To multiply the numbers in scientific notation, you multiply the coefficients and add the exponents:
Weight of all ants = 3 × 1 × 10^-6 × 10^16 kg
Weight of all ants = 3 × 10^(16-6) kg
Weight of all ants = 3 × 10^10 kg
Therefore, the approximate weight of all the ants in the world is 3 × 10^10 kilograms.
To calculate the weight of all the ants in the world, we need to multiply the weight of an individual ant by the total number of ants.
Given:
Weight of an ant = 3×10^-6 kg
Number of ants = 1×10^16
To multiply numbers in scientific notation, we multiply the coefficients and add the exponents.
Coefficient calculation:
3 × 1 = 3
Exponent calculation:
10^-6 × 10^16 = 10^(-6 + 16) = 10^10
Therefore, the weight of all the ants in the world is approximately 3 × 10^10 kg.
