Question

If 10mL of acetic acid is diluted with 200mL water, what is the percent by volume of acetic acid in the solution?

Answer 1

Answer:

5%

Step-by-step explanation:

Volume of original acetone before dilution = 10ml

Volume of diluted solution = 200ml

Unknown:

Percent volume of acetone in the solution = ?

Solution:

To find the percent volume of acetone in the diluted solution, use the expression below;

 Percent volume of acetone = \frac{volume of original acetone}{diluted volume} x 100dilutedvolumevolumeoforiginalacetonex100

Insert the parameters and solve;

 Percent volume of acetone  = \frac{10}{200}20010  x 100 = 5%

Answer 2

Given,

Quantity of acetic acid $\[ = 10ml\]$

Quantity of water $\[ = 200ml\]$

Solution,

Calculate the percent by volume of acetic acid in the solution.

$\[ = \frac{{10}}{{200 + 10}} \times 100\]$

$\[ = \frac{{100}}{{21}}\]$

$\[ = 4.76\% \]$

The percent by volume of acetic acid in the solution is $\[4.76\% \]$.
