Calculating the Percentage of St. John's Wort in the Mixture

To calculate the percentage of St. John's Wort in the mixture, we can use the given ratio of St. John's Wort to Chamomile, which is 8:17.

Step 1: Calculate the total parts in the mixture. The total parts in the mixture are the sum of the parts of St. John's Wort and Chamomile, which is 8 + 17 = 25 parts.

Step 2: Calculate the percentage of St. John's Wort in the mixture. To find the percentage of St. John's Wort in the mixture, we can use the following formula: \[ \text{Percentage of St. John's Wort} = \frac{\text{Parts of St. John's Wort}}{\text{Total parts}} \times 100 \]

Substituting the values, we get: \[ \text{Percentage of St. John's Wort} = \frac{8}{25} \times 100 = 32\% \]

Therefore, the percentage of St. John's Wort in the mixture is 32%.
