Question

25. How many ml of a .0023M strontium hydroxide solution are needed to completely react 15.0 mL of 0.012M hydrochloric acid?

Answer 1

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.

Step-by-step explanation:

Given:
`M_(1)` = 0.0023 M,
`V_(1)` = ?

`V_(2)` = 15.0 mL,
`M_(2)` = 0.012 M

Formula used to calculate volume of strontium hydroxide solution is as follows.

`M_(1)V_(1) = M_(2)V_(2)`

Substitute the values into above formula as follows.

`M_(1)V_(1) = M_(2)V_(2)\\0.0023 M * V_(1) = 0.012 M * 15.0 mL\\V_(1) = 78.26 mL`

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.
