<span>The Answer </span>should be<span> .074 M</span>
Explanation:
Reaction:
Cu + 2AgC₂H₃O₂ → Cu(C₂H₃O₂)₂ + 2Ag
The problem is to split the reaction into oxidation and reduction halves:
The oxidation half is the sub-reaction that undergoes oxidation
The reduction half is the one that undergoes reduction:
The ionic equation:
Cu + 2Ag⁺ + 2C₂H₃O₂⁻ → Cu²⁺ + 2C₂H₃O₂⁻ + 2Ag
Oxidation half:
Cu → Cu²⁺ + 2e⁻
Reduction half:
2Ag⁺ + 2e⁻ → 2Ag
C₂H₃O₂⁻ is neither oxidized nor reduced in the reaction.

A mixture in which composition is constant throughout the mixture is said to be homogeneous mixture.
Now, oil and vinegar dressing is not considered as a homogeneous mixture because composition is not uniform.
Concrete is made up of three components. Thus, composition is not uniform, so it is not a homogeneous mixture.
A mixture of salt and pepper, when salt is mixed in pepper then the mixture is not uniform as white flecks of salt and black flecks of pepper can be seen in the mixture. Thus, it is not a homogeneous mixture.
Salt water is uniform mixture. Thus, it is a homogeneous mixture.
Thus, salt water is the correct answer.
