To figure out total mass, multiply the total amount of humans and ants to their mass. Total number of ants x mass of one individual:(5 times 10 to the power of 16) times (3 times 10 to the power of -6)

1 answer

5 x 10^16 x 3 x 10^-6 = 15 x 10^10 = 1.5 x 10^11

Therefore, the total mass of ants is 1.5 x 10^11.
