Answer :
Final answer:
The concentration of the final solution is 1.437 M.
Explanation:
To calculate the concentration of the final solution, we can use the formula:
C₁V₁ + C₂V₂ = C₃V₃
where C₁ and V₁ are the concentration and volume of the first solution, C₂ and V₂ are the concentration and volume of the second solution, and C₃ and V₃ are the concentration and volume of the final solution.
In this case, we have the following values:
Substituting these values into the formula, we get:
(1.69 M)(37.2 ml) + (0.891 M)(17.40 ml) = C₃V₃
Simplifying the equation:
63.108 M·ml + 15.3984 M·ml = C₃V₃
78.5064 M·ml = C₃V₃
Since we are calculating the concentration of the final solution, we can assume that the volume of the final solution is the sum of the volumes of the two solutions:
V₃ = V₁ + V₂ = 37.2 ml + 17.40 ml = 54.60 ml
Substituting this value into the equation:
78.5064 M·ml = C₃(54.60 ml)
Solving for C₃:
C₃ = 78.5064 M·ml / 54.60 ml = 1.437 M
Therefore, the concentration of the final solution is 1.437 M.
