Answer: The concentration of given phosphoric acid solution is 0.357 M.
Explanation:
Given: [tex]V_{1}[/tex] = 25.00 mL, [tex]M_{1} = ?[/tex]
[tex]V_{2}[/tex] = 35.77 mL, [tex]M_{2}[/tex] = 0.250 M
Formula used to calculate the concentration of phosphoric acid is as follows.
[tex]M_{1}V_{1} = M_{2}V_{2}[/tex]
Substitute the values into above formula as follows.
[tex]M_{1}V_{1} = M_{2}V_{2}\\M_{1} \times 25.00 mL = 0.250 M \times 35.77 mL\\M_{1} = 0.357 M[/tex]
Thus, we can conclude that concentration of given phosphoric acid solution is 0.357 M.
