To determine how much adrenaline is in a 1 ml ampoule of adrenaline 1:1000, let's break down the concentration notation and understand what it means.
1. The notation "1:1000" indicates a ratio, meaning there is 1 part of adrenaline in 1000 parts of the solution.
2. This can be interpreted as follows:
- For every 1000 ml of the solution, there is 1 g (gram) of adrenaline.
- Since 1 g is equal to 1000 mg (milligrams), this translates to 1 mg of adrenaline in 1000 ml of solution.
3. To find out how much adrenaline is in 1 ml:
- By dividing the concentration, we see that if there is 1 mg of adrenaline in 1000 ml, then in 1 ml, there would be [tex]\(\frac{1 \text{ mg}}{1000 \text{ ml}}\)[/tex]:
[tex]\[\frac{1 \text{ mg}}{1000 \text{ ml}} \times 1 \text{ ml} = 1 \text{ mg/1000 ml} \times 1000/1000 \text{ ml} = 1 \text{ mg / 1 ml} = 1 \text{ mg}\][/tex]
So, a 1 ml ampoule of adrenaline 1:1000 contains 1 mg of adrenaline.
The correct option is:
C. 1 mg
