Answer:- Mass of copper piece is 290 gram.
Solution:- We know that, mass = density * volume
density of copper is given as 8.96 gram per mL.
Volume of copper piece is the rise change in volume.
Volume of copper piece = 137 mL - 105 mL = 32 mL
Let's multiply the volume by density to calculate the mass of copper:
mass of copper =
mass of copper = 286.72 g
Volume has two significant figures, so if we round the mass to two significant figures then it becomes 290 g.

The symbol for Krypton is Kr.
<u>Answer:</u> Copper (I) iodide will precipitate first.
<u>Explanation:</u>
We are given:
of CuCl =
of CuI =
Concentration of
Concentration of
Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.
Putting values in above equation, we get:
Concentration of copper (I) ion =
Putting values in above equation, we get:
Concentration of copper (I) ion =
For the precipitation of copper (I) ions, we need less concentration of copper (I) ions. So, copper (I) iodide will precipitate first.
