Using the value of Ksp=6×10−51 for Ag2S, Ka1=9.5×10−8 and Ka2=1×10−19 for H2S, and Kf=1.1×105 for AgCl−2, calculate the equilibrium constant for the following reaction: Ag2S(s)+4Cl−(aq)+2H+(aq)⇌2AgCl−2(aq )+H2S(aq)

A4.86 g piece of metal was placed in a graduated cylinder containing 15.5 ml of water. the water level rose to 17.3 ml. what is the density of the metal. i need the steps of how to solve it to so i can use a formula to work out other problems.
