To figure out total mass, multiply the total amount of humans and ants to their mass. Total number of humans x mass of one individual: (7.5 times 10 to the power of 9) times (6.2 times 10 to the power of 1).Multiply base numbers.

Answer 1

(7.5 x 10^9) x (6.2 x 10^1) = 4.65 x 10^10

Now multiply the powers of 10.

9 + 1 = 10

So, the total mass of humans is 4.65 x 10^10 kg.

Next, calculate the total mass of the ants. Total number of ants x mass of one individual: (2.3 times 10 to the power of 14) times (3.1 times 10 to the power of -5). Multiply base numbers.

(2.3 x 10^14) x (3.1 x 10^-5) = 7.13 x 10^9

Now multiply the powers of 10.

14 + (-5) = 9

So, the total mass of ants is 7.13 x 10^9 kg.

To find the total mass of humans and ants, add their masses together:

4.65 x 10^10 kg + 7.13 x 10^9 kg = 4.65 x 10^10 kg + 0.713 x 10^10 kg = 5.363 x 10^10 kg

Therefore, the total mass of the humans and ants combined is 5.363 x 10^10 kg.
