Question #8edc0

Answer 1

The final concentration is `2.0 M`

Explanation:

To obtain the final molarity, we can use the equation below:

According to the information provided, we know the following information:

`M_1` = 10.0 M
`V_1` = 25 mL
`V_2` = 125 mL

Since we don't know `M_2`, the equation has to be rearranged by dividing both sides by `V_2` to get `M_2` by itself:

`M_2 = (M_1 xx V_1)/V_2`

Now, just plug in the known values and solve for the second concentration:

`M_2 = (10.0 M xx 25 cancel"mL")/(125cancel"mL")`

`M_2` = 2.0 M
