How many milligrams are there in 0.5 g?
Answer and explanation
Correct answer: D. 500 mg
- Step 1: 1 g is 1,000 mg. Step 2. 0.5 x 1,000 = 500 mg. Answer: 500 mg. Why not the others: 50.0005 mg: 1 g was treated as 100 mg. 0.0005 mg: the value was divided instead of multiplied by 1000. 5000.0005 mg: an extra factor of 10 was applied.
