Question

Of an 8 M solution of HCI, 1 L is diluted to 2 M. What is the volume of the diluted solution?

Answer 1

Answer: The volume of diluted solution is 4 L

Explanation:

According to the dilution law,

$M_1V_1=M_2V_2$

where,  

$M_1$ = molarity of stock $HCl$ solution = 8 M

$V_1$ = volume of stock $HCl$ solution = 1 L  

$M_1$ = molarity of diluted $HCl$ solution = 2 M

$V_1$ = volume of diluted $HCl$ solution = ?

Putting in the values we get:

$8M\times 1L=2M\times V_2$

$V_2=4L$

Therefore, volume of diluted solution is 4 L
