Question

How many milliliters of pure acetic acid should Suzanne mix with 100 mL of 2% acetic acid to produce

a solution that is 8% acetic acid?

Answer 1

To find the volume of pure acetic acid required, we can use the concept of moles. The volume of pure acetic acid required is 100 mL.

Step-by-step explanation:

To find the number of milliliters of pure acetic acid required, we can use the concept of moles and the equation:

Moles of pure acetic acid/Moles of 2% acetic acid = Volume of pure acetic acid/Volume of 2% acetic acid

Since the concentration of the initial solution is given as 2%, we can calculate the number of moles of acetic acid in 100 mL of the solution:

0.02 moles/L x 0.1 L = 0.002 moles of acetic acid

Now, we can use the equation mentioned earlier to find the number of milliliters of pure acetic acid required:

0.002 moles/1 = Volume of pure acetic acid/Volume of 2% acetic acid

Volume of pure acetic acid = 0.002 moles x (100 mL / 0.002 moles)

Volume of pure acetic acid = 100 mL
