The volume of the silver piece is 12 mL.
To find the volume of the silver piece, we need to determine the change in volume caused by immersing it in water. This change is equal to the volume of water displaced by the silver piece.
The initial volume of water is 50 mL, and after immersing the silver piece, it rises to 62 mL. Therefore, the change in volume is:
Change in volume = Final volume - Initial volume
Change in volume = 62 mL - 50 mL
Change in volume = 12 mL
Hence, the volume of the silver piece is 12 mL.
