Answer 1

Answer: There are 20 milliliters of 1.0 M HCl is required to be diluted to make 200 mL of a 0.1 M solution.

Step-by-step explanation:

Given:
`M_(1)` = 1.0 M,
`V_(1)` = ?

`M_(2)` = 0.1 M,
`V_(2)` = 200 mL

Formula used is as follows.

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

Substitute values into the above formula as follows.

`M_(1)V_(1) = M_(2)V_(2)\\1.0 M * V_(1) = 0.1 M * 200 mL\\V_(1) = (0.1 M * 200 mL)/(1.0 M)\\= 20 mL`

Thus, we can conclude that there are 20 milliliters of 1.0 M HCl is required to be diluted to make 200 mL of a 0.1 M solution.
