Yes it could.
Mass times volume isn't a formula for anything. You may be confused with mass divided by volume, which is the formula for density.
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.
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.
