Question

4.1: solution concentration/water as a solvent a chemist dilutes 60.0 ml of 4.50 m potassium permanganate to make a 1.25 m solution. what is the final volume of the solution?

Explanation:

Step1: Use dilution formula

$M_1V_1 = M_2V_2$
where $M_1 = 4.50\ M$, $V_1=60.0\ mL$, $M_2 = 1.25\ M$, and $V_2$ is the final - volume we want to find.

Step2: Rearrange the formula to solve for $V_2$

$V_2=\frac{M_1V_1}{M_2}$

Step3: Substitute the values

$V_2=\frac{4.50\ M\times60.0\ mL}{1.25\ M}$
$V_2 = 216\ mL$

Answer:

$216\ mL$
