The concentration of the diluted solution will be 2.44%.
<h3>Dilution problem</h3>
From the equation of dilution:
(M1)(V1) = (M2)(V2).
where M1 = concentration before dilution, M2 = concentration after dilution, V1 = volume before dilution, and V2 = volume after dilution.
In this case:
V1 = 17.06 mL
V2 = 50.00 mL
M1 = 7.16%
M2 = ?
M2 = (M1)(V1)/(V2)
= 7.16 x 17.06/50
= 2.44%
Thus, the concentration of the diluted solution is 2.44%.
