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.
