According to the Rutherford model of the atom, the atomic nucleus contains -all of the atom's electrical charge, but none of the atom's mass
-all of the atom's mass, but none of the atom's electrical charge
-most of the atom's mass and all of the atom's negative charge
-most of the atom's mass and all of the atom's positive charge

most of the atom's mass and all of the atom's positive charge

Explanation:

Based on Rutherford's model most of the atom's mass and all of the positive charges are concentrated in the nucleus.

Rutherford performed the gold foil experiment that gave the modelling of the atomic structure a boost.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.
