Answer 1

A 250 mg tablet of cephalexin contains 250,000 mcg of cephalexin.

Step-by-step explanation:

To calculate how many micrograms (mcg) of cephalexin are in a 250 mg tablet, you need to use a conversion factor, knowing that 1 milligram (mg) equals 1,000 micrograms (mcg). Therefore:

• 250 mg × 1,000 mcg/mg = 250,000 mcg

So, a tablet containing 250 mg of cephalexin has 250,000 mcg of cephalexin. Therefore, the correct answer is c. 250,000 mcg.
