Question

1. transfer the solution into a 250 ml beaker and set this solution aside to for later use. 9. pour 33 ml of juice a followed by 67 ml of water into the 100 ml graduated cylinder. record the percent strength of juice a in table 5. with 28 ml of juice b in a graduated cylinder. record the percent

Explanation:

To determine the percent strength (concentration) of Juice A, we use the formula for volume - by - volume (v/v) percentage concentration:

Step 1: Identify the volumes of solute and solution

The volume of Juice A (solute) is \(V_{solute}=33\space mL\).
The volume of water (solvent) is \(V_{solvent} = 67\space mL\).
The total volume of the solution \(V_{solution}=V_{solute}+V_{solvent}\)

Step 2: Calculate the total volume of the solution

\(V_{solution}=33\space mL + 67\space mL=100\space mL\)

Step 3: Calculate the percent strength

The formula for percent strength (v/v) is \(\text{Percent Strength}=\frac{V_{solute}}{V_{solution}}\times100\%\)

Substitute \(V_{solute} = 33\space mL\) and \(V_{solution}=100\space mL\) into the formula:

\(\text{Percent Strength}=\frac{33}{100}\times 100\% = 33\%\)

Answer:

The percent strength of Juice A is \(33\%\)
