Question

How many milliliters of 1.5 M H.So, are needed to exactly

neutralize 20. milliliters of a 0.8 M KOH solution?

Answer 1

Answer: A volume of 10.66 mL of 1.5 M H is required to exactly neutralize 20. milliliters of a 0.8 M KOH solution.

Step-by-step explanation:

Given:
`M_(1)` = 1.5 M,
`V_(1)` = ?

`V_(2)` = 20 mL,
`M_(2)` = 0.8 M

Formula used to calculate the volume 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)\\1.5 M * V_(1) = 0.8 M * 20 mL\\V_(1) = 10.66 mL`

Thus, we can conclude that a volume of 10.66 mL of 1.5 M H is required to exactly neutralize 20. milliliters of a 0.8 M KOH solution.
