Question

can someone correct me if i set up this problem incorrectly? (it'll be in the comments)

Answer 1

yes you have set it up correctly. Well that's what I believe.

Answer 2

10^6 micrograms = 1 gram
48.2 micrograms = 48.2 / 10^6 = 48.2 x 10^-6 = 4.82 x 10 x 10^-6 =
4.82 x 10^-5 gram.

10^3 grams = 1 Kg
4.82 x 10^-5 grams = 4.82 x 10^-5 / 10^3 = 4.82 x 10^-5 x 10^-3 =
4.82 x 10^-8 Kg.
