Answer:
e) 1000 μg
Step-by-step explanation:
When we need to change of units is very important to know equivalence and use conversion factors to change from one unit to another unit.
1Ton = 1000Kg
1Kg = 1000g
1g = 1000mg
1mg = 1000 μg
In this case, always 1mg will be equal to 1000 μg as well as 2mg will be 1000μg
