Final answer:
To determine the number of mL(s) to give, calculate the volume of the stock solution that contains 800 mg of ABC. You will give approximately 0.533 mL(s) of the stock solution.
Step-by-step explanation:
To determine the number of mL(s) to give, we need to calculate the volume of the stock solution that contains 800 mg of ABC. First, we need to find the concentration of the stock solution:
Concentration = Stock / Volume = 1500 mg/mL
Next, we can set up a proportion using the concentration and the desired amount of ABC:
Volume of stock solution / 1500 mg/mL = 800 mg / 1
Now we can solve for the volume of the stock solution:
Volume of stock solution = (800 mg * 1) / 1500 mg/mL = 0.533 mL
So, you will give approximately 0.533 mL(s) of the stock solution.
