11. When applying essential oils through massage, it is necessary to prepare a mixture. When creating a mixture for massage: __ drops of essential oil should be diluted with 5 ml (one teaspoon) of cold-pressed vegetable oil, cream or gel. Using a 1% to 5% dilution, the amount of essential oil absorbed from a whole body massage should normally be __ ml to __ ml. a. 5-6 drops, 0.003 to 0.2 ml b. 3-4 drops. 0.001 to 0.5 ml C. 4-5 drops, 0.003 to 0.1 ml d. 10 drops, 0 .001 to 0.2 ml e. 1-2 drops, 0.002 to 0.3 ml

The correct answer is a. $5-6$ drops, 0.003 to 0.2 ml.<br /><br />When applying essential oils through massage, it is recommended to dilute the essential oils with a carrier oil, such as cold-pressed vegetable oil, cream, or gel. The typical dilution ratio for massage is between 1% to 5%, which means 1 to 5 drops of essential oil per 1 teaspoon (5 ml) of carrier oil.<br /><br />To calculate the amount of essential oil needed for a whole body massage, we can use the following formula:<br /><br />Amount of essential oil (ml) = (Dilution percentage / 100) x Carrier oil volume (ml)<br /><br />For a 1% dilution, the amount of essential oil would be:<br />Amount of essential oil = (1 / 100) x 5 ml = 0.05 ml<br /><br />For a 5% dilution, the amount of essential oil would be:<br />Amount of essential oil = (5 / 100) x 5 ml = 0.25 ml<br /><br />Therefore, the amount of essential oil absorbed from a whole body massage should normally be between 0.003 ml to 0.2 ml, which corresponds to option a.
