Question

How much pure acid is in 440 milliliters of a 17​% ​solution?

Answer 1

To find out how much pure acid is in a 440 milliliters solution that is 17% acid, you can use the following formula:

\[
\text{Amount of pure acid} = \text{Total volume of solution} \times \text{Concentration of acid}
\]

In this case:

- Total volume of solution = 440 mL
- Concentration of acid = 17% = 0.17 (when expressed as a decimal)

Now, plug in the values:

\[
\text{Amount of pure acid} = 440 \, \text{mL} \times 0.17
\]

Calculating that gives:

\[
\text{Amount of pure acid} = 74.8 \, \text{mL}
\]

So, there are **74.8 milliliters** of pure acid in the 440 milliliters of the 17% solution.
