The new concentration of the solution is 0.89 M.

Explanation:

In chemistry, dilution is the reduction in concentration of a chemical in a solution. This is accomplished by adding more solvent to the same amount of solute.

So, in a dilution, the amount of solute does not vary, but the volume of the solvent varies: as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.

In a dilution the expression is used:

Ci*Vi = Cf*Vf

where:

Ci: initial concentration Vi: initial volume Cf: final concentration Vf: final volume

In this case:

Ci= 2.5 M Vi= 250 mLCf=? Vf= 700 mL

Replacing:

2.5 M* 250 mL= Cf* 700 mL

Solving:

$Cf=\frac{2.5 M*250 mL}{700 mL}$

Cf= 0.89 M

The new concentration of the solution is 0.89 M.

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
