Answer: There are 78.26 mL of a 0.0023M strontium hydroxide solution are needed to completely react 15.0 mL of 0.012M hydrochloric acid.

Explanation:

Given: [tex]M_{1}[/tex] = 0.0023 M,          [tex]V_{1}[/tex] = ?

[tex]V_{2}[/tex] = 15.0 mL,           [tex]M_{2}[/tex] = 0.012 M

Formula used to calculate volume of strontium hydroxide solution 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}\\0.0023 M \times V_{1} = 0.012 M \times 15.0 mL\\V_{1} = 78.26 mL[/tex]

Thus, we can conclude that there are 78.26 mL of a 0.0023M strontium hydroxide solution are needed to completely react 15.0 mL of 0.012M hydrochloric acid.
