The answer depends on the density of the substance because milliliters are units of volume and milligrams are units of mass. 150 ml of pure water at standard temperature and pressure have a mass of 150 mg.
You cannot associate weight with volume without knowing the density. If you find this out. Density is mass/volume
There's no single answer to that, as ml is volume and mg is weight. Depending on the density of the substance the answer will be different.
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.
12.5mg
This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, grams (g) and milligrams (mg) are measures of weight or mass.
45ml of the elixir
11/5 mL 1.2 mL
One milliliter is equal to one gram (1 mL= 1 g), and there are 1,000 milligrams in a liter, so 3 mL is equal to 3,000 milligrams and 100 mg is equal to .1 mL.
1 l is equal to 1000 ml. 1.8l is equal to 1800 ml.
Only if the density or concentration is 1 mg/ml
That is approximately 227 ml
Only if the density or concentration is 2 grams per ml
There's no single answer to that, as ml is volume and mg is weight. Depending on the density of the substance the answer will be different.
Assuming a density of 1g/ml, 1,000,000mg
1 ml usually equals 10 mg. but there are different potencies. I think it's usually 10 per 1 ml or 5 per 1 ml.
A millilitre and a cubic centimetre are the same measurement - therefore, 230 cubic centimetres is equal to 230 millilitres.
This is not a valid comparison; milligrams (mg) is a measure of weight or mass while milliliters (mL or ml) measure volume.
