Given the different molecular weights, dipole moments, and molecular shapes, why are their molar volumes nearly the same? o because in the gas phase molecules do not interact with each other because molecules of a gas have very low kinetic energy. because most of the volume occupied by the substance is empty space. because these factors compensate each other

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
