How do you convert from grams of a substance to volume?

To convert grams of a substance to volume, you need to know the substance's density, which is typically expressed in grams per milliliter (g/mL) or grams per cubic centimeter (g/cm³). Use the formula: Volume (mL) = Mass (grams) / Density (g/mL). By dividing the mass of the substance by its density, you can calculate the volume.
