Express 250 mg in grams.
Answer and explanation
Correct answer: B. 0.25 g
- Step 1: 1,000 mg make 1 g. Step 2. 250 / 1,000 = 0.25 g. Answer: 0.25 g. Why not the others: 250000 g: the value was multiplied instead of divided by 1000. 2.5 g: 1 g was treated as 100 mg. 0.025 g: an extra factor of 10 was applied.
