Answer:
0.125 mg
Explanation:
<em>The correct answer would be 0.125 mg</em>
<u>According to the conversion factor, one milligram of a sample is equivalent to one thousand micrograms of the same sample.</u>
milligram = ![10^{-3}](https://tex.z-dn.net/?f=10%5E%7B-3%7D)
microgram = ![10^{-6}](https://tex.z-dn.net/?f=10%5E%7B-6%7D)
Hence,
1 milligram = 1000 micrograms or 1 microgram =
milligram
Therefore, 125 micrograms will be:
125/1000 = 0.125 milligram
