A "gram" is a unit of mass
A "cc" or "cubic centimeter" is a unit of volume
An "ounce" is a unit of mass but can be a unit of volume, e.g., fluid ounce.
To calculate volume from mass and vice-versa, you need to know the specific gravity or density of the substance in question. I suggest you re-write your question using a specific substance to convert.
