Question

what volume of a 1.00-M Fe(NO3)3 solution can be diluted to prepare 1.00 L of a solution water with a concentration of 0.250 M?

Answer 1

Answer: The volume of concentrated solution is 0.250 L

Explanation:

To calculate the volume of concentrated solution, we use the equation:

$M_1V_1=M_2V_2$

where,

$M_1\text{ and }V_1$ are the molarity and volume of the concentrated solution

$M_2\text{ and }V_2$ are the molarity and volume of diluted solution

We are given:

$M_1=1.00M\\V_1=?L\\M_2=0.250M\\V_2=1L$

Putting values in above equation, we get:

$1.00\times V_1=0.250\times 1\\\\V_1=0.250L$

Hence, the volume of concentrated solution is 0.250 L
