Question

In an experiment 25.0 mL of 0.100 M KI was diluted to 50.0 mL. Calculate the molarity of the diluted solution

Answer 1

Answer:

The molarity is "0.050 M".

Explanation:

The given values are:

M1 = 0.100 M

M2 = ?

V1 = 25.0 mL

V2 = 50.0 mL

As we know,

⇒ $M1\times V1=M2\times V2$

Or,

⇒ $M2=\frac{M1\times V1}{V2}$

By putting the values, we get

          $=\frac{0.100\times 25}{50}$

          $=\frac{2.5}{50}$

          $=0.05 \ M$
