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 = 
microgram = 
Hence,
1 milligram = 1000 micrograms or 1 microgram =
milligram
Therefore, 125 micrograms will be:
125/1000 = 0.125 milligram
Explanation:
In normal atmosphere, analytical reagents may absorb water molecules that may affect the results of chemical reactions. So, in order to get accurate results from these analytical regents, they must be stored in a dessicated atmosphere or heated before being used so that the water molecules must dry away.
