question 2 (3 points)
if 8 tablespoons of extract are mixed with distilled water to total 300 ml, what is the final concentration (v/v)?

Explanation:

Step1: Convert tablespoons to milliliters

1 tablespoon is approximately 14.7868 mL. So, 8 tablespoons is $8\times14.7868 = 118.2944$ mL.

Step2: Calculate (v/v) concentration

The formula for (v/v) concentration is $\frac{\text{Volume of solute}}{\text{Volume of solution}}\times100\%$. Here, solute volume is 118.2944 mL and solution volume is 300 mL. So, concentration is $\frac{118.2944}{300}\times100\% \approx 39.43\%$.

Answer:

Approximately 39.43% (If we consider 1 tablespoon = 15 mL for approximation, 8*15 = 120 mL, then $\frac{120}{300}\times100\% = 40\%$)
