20 grams are equal to what volume in mL?

Answer 1

This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.

Answer 2

The volume of 20 grams depends on the density of the substance. To convert grams to milliliters, you need to know the density of the substance. The formula to convert is: volume (in mL) = mass (in g) / density (in g/mL).

Answer 3

This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.
