Isotopes. They conatin atoms of the same element with the same proton number (atomic no) but different number of neutrons (atomic mass = protons + neutrons)
What you would want to do here is dividing mass by density. In fact, density is referred to as a ratio of mass to volume. There is no need for any unit conversion as they are already comparable. So the result should be 105g / 11.3g/ml =9.3ml.
English is not my first language, so sorry for language issues of any kind.
