Question

If I dilute 250 mL of 0.50 M lithium acetate solution to a volume of 750 mL, what will the concentration of this solution be?​

Answer 1

The right answer is "0.17 M".

Step-by-step explanation:

The given values are:

Volume,

V₁ = 250 mL

V₂ = 750 mL

Molarity,

M₁ = 0.50 M

M₂ = ?

As we know,

⇒
`M_1 V_1=M_2 V_2`

or,

⇒
`M_2=(M_1 V_1)/(V_2)`

On substituting the values, we get

⇒
`=(0.50* 250)/(750)`

⇒
`=(125)/(750)`

⇒
`=0.17 \ M`
