Question

Please help me with this question, if you can! :)
Your teacher has 4.0 L of a 15% (v/v) solution of sulfuric acid in water. What will the volume of the solution be if it is diluted to 10% (v/v)?

Answer 1

Answer: The volume of the solution be if it is diluted to 10% (v/v) is 6.0 L

Explanation:

According to the dilution law,

$C_1V_1=C_2V_2$

where,

$C_1$ = concentration of pure acid solution = 15 %

$V_1$ = volume of pure acid solution = 4.0 L

$C_2$ = concentration of diluted acid solution= 10%

$V_2$ = volume of diluted acid solution= ?

Putting in the values we get:

$15\times 4.0=10\times V_2$

$V_2=6.0L$

Thus the volume of the solution be if it is diluted to 10% (v/v) is 6.0 L
