Visit this density simulation at the link provided and click the "turn fluid into water" button to adjust the density of liquid in the beaker to 1.00 g/mL. Use the water displacement approach to measure the mass and volume of the unknown material (select the green block with question marks). What are the mass and volume of the material?

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
