Question

What is the new concentration of a solution of CaSO3 if 10.0 mL of a 2.0 M CaSO3 solution is diluted to 100 ml?

Answer 1

Answer: The new concentration of a solution of
`CaSO_(3)` is 0.2 M 10.0 mL of a 2.0 M
`CaSO_(3)` solution is diluted to 100 mL.

Step-by-step explanation:

Given:
`V_(1)` = 10.0 mL,
`M_(1)` = 2.0 M

`V_(2)` = 100 mL,
`M_(2)` = ?

Formula used to calculate the new concentration 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)\\10.0 mL * 2.0 M = M_(2) * 100 mL\\M_(2) = 0.2 M`

Thus, we can conclude that the new concentration of a solution of
`CaSO_(3)` is 0.2 M 10.0 mL of a 2.0 M
`CaSO_(3)` solution is diluted to 100 mL.
