The weights of four different insects are given below. Insect A: 2.19*10^-4 g; Insect B: 5.00*10^-3 g; Insect C: 9.0*10^-2 g; Insect D: 1.50*10^-3 g What is the order of these insects from heaviest to lightest?

The correct choice is D

Insect A: 2.19*10^ (-4) g = 0.000219 g

Insect B: 5.00*10^ (-3) g = 0.005000 g

Insect C: 9.00*10^ (-2) g = 0.090000 g

Insect D: 1.50*10^ (-3) g = 0.001500 g

Then, the order of these insects from heaviest to lightest is:

Insect C, Insect B, Insect D and Insect A
