Final answer:
To calculate the number of milliliters (mL) of a 0.8 mg adrenaline solution, we can use the information provided on the label which states that it is a 1:1000 solution.
Step-by-step explanation:
To calculate the number of milliliters (mL) of a 0.8 mg adrenaline solution, we need to use the information provided on the label which states that it is a 1:1000 solution. This means that there is 1 gram (1000 mg) of adrenaline in 1000 mL of solution. Therefore, to find the mL for 0.8 mg, we can set up the following proportion:
1 gram x mL
------ = ------
1000 mg 0.8 mg
Cross-multiplying and solving for mL, we get:
x = (0.8 mg * 1000 mL) / 1000 mg
x = 0.8 mL.
