At a certain lab, the average mass of one ant is measured to be 2.9\times 10^{-6}2.9×10 −6 kilograms. Use scientific notation to express the mass of 6060 ants.

Answer 1

2.9 x 10^-6 kg = mass per ant times x 6,060 ants

= 2.9 x10^-6 x 6.06 x 10^3

= 2.9 x 6.06 x 10^-6 x 10^3

= 17.574 x 10^(-6+3)

= 1.7574 x 10^1 x 10^-3

= 1.7574 x 10^-2 kg

= about average 1.8 x 10^-2 kilograms for 6,060 ants, in scientific notation

which = 0.018 kg
