What is 4.5 grams equal to in mL?

Answer 1

To convert grams to milliliters, you need to know the density of the substance in question. Density is the mass of a substance per unit volume. Since grams measure mass and milliliters measure volume, the conversion factor between the two units depends on the density of the specific substance. Without knowing the density of the substance, it is not possible to accurately convert 4.5 grams to milliliters.

Answer 2

There is no equivalence.

A gram is a measure of mass. A milliitre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.

If you are not convinced, consider a millilitre of air. How many grams? Next consider a millilitre of Mercury. How many grams?

The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
