Yes it could.
Lets say there are 3 isotopes of an element. A is 25% and has a mass of 24, B is 40% and has a mass of 25, and C is 35% and has a mass of 26. Multiply the mass by the percentage in decimal form and add all together. (.25 x 24) + (.40 x 25) + (.35 x 26) = weighted average. If there are more then continue (percent in decimal form x mass) and keep adding.
Mass times volume isn't a formula for anything. You may be confused with mass divided by volume, which is the formula for density.
The atomic mass of an element is the weighted average of masses of the isotopes of the element, weighted in proportion to their abundance.
Kg is a unit of mass, while m is a unit of distance, so the conversion you request is not possible.
