Answer: 1L = 1000 mL
Explanation:
1. 1 milligram (mg) is equal to 0.001 gram (gm), so 10mg = 0.01. The first choice is incorrect
2. 1 liter (L) = 1000 milliliter (mL) so the second choice is correct
3. 1 microgram (mcg) is equal to 0.001 milligram (mg), so the third choice is incorrect.
4. 1 liter (L) = 1000 milliliter (mL), so the fourth choice is evidently incorrect. (1000 L would be 1,000,000 mL)
