Final answer:
To give 23 mg of valium from a 10 mL solution containing 100 mg, you would administer 2.3 mL since the concentration of the solution is 10 mg/mL.
Step-by-step explanation:
If you needed to give 23 mg of valium, and you have a solution containing 100 mg in 10 mL, you would first determine how many mg of valium are in 1 mL of solution. Since there are 100 mg in 10 mL, you divide 100 mg by 10 mL to get 10 mg/mL. Now, to find out how many mLs contain 23 mg of valium, you divide the desired dose, 23 mg, by the concentration, which is 10 mg/mL.
The calculation is as follows: 23 mg / 10 mg/mL = 2.3 mL. Therefore, you would need to administer 2.3 mL of the solution to deliver a dose of 23 mg of valium.
