How many milligrams equals 50 milliliters?

Answer 1

As asked, the question is incomplete. The two measurements are not interchangeable.

Grams (of which milligrams are a derived unit) are a unit are mass; whereas liters (of which milliliters are a derived unit) are a unit of volume.

The two are connected by density (mass = density � volume) which depends upon the substance (and temperature and pressure). Thus how many milligrams in 50 ml would depend upon the substance (and its temperature and pressure).

When dealing with medicines, a dosage is given as so many milligrams per so many milliters thus how many milligrams equals 50 ml would depends upon the drug [and] concentration given.

Answer 2

The equivalence between milligrams and milliliters depends on the substance's density. If we assume water-like density, 50 milliliters would be equivalent to 50,000 milligrams, as 1 milliliter of water is roughly equivalent to 1 gram.

Answer 3

Grams measure weight. Liters measure volume. They do not interchange.

Answer 4

Anywhere from zero to infinity, depending on the specific substance.
