Final answer:
The concentration of the diluted solution is 2.36 M.
Step-by-step explanation:
To find the concentration of the diluted solution, we can use the dilution equation:
C1V1 = C2V2
where
C1 and V1 are the concentration and volume of the stock solution
C2 and V2 are the concentration and volume of the diluted solution
In this case, the stock concentration is 5.00 M and the volume is 0.850 L.
The volume of the diluted solution is 1.80 L. Substituting these values into the equation:
(5.00 M)(0.850 L) = C2(1.80 L)
C2 = (5.00 M)(0.850 L) / (1.80 L) = 2.36 M
Therefore, the concentration of the diluted solution is 2.36 M, which is not one of the given options.
