Question
the mass of the isolated acetamilhophel lll youl hocoook. funnel for at least 15 minutes. Record Determine the percent yield of the product. Preparation of Acetaminophen Standards Four standard solutions will be prepared for you by dissolving 25 mg of acetaminophen in 50 mL of distilled water. The four standard solutions will then be made by diluting this acetaminophen solution with water as indicated in Table 1 Table 1-amounts of water and acetaminophen solutions to make each standard solution. Acetaminophen solution (mL) 1.5 0.5 Standard # Water (mL)A 4 4.5 4 100Explanation / Answer
Initial concentration C1 = 25 mg /50mL = 0.5 milligram / mL
-STANDARD 1:
Using, C1V1 = C2V2
Where C1, C2 = initial and final concentration
V1, V2 = initial and final volumes
0.5 mg /mL * 2 mL = C2 * (3+2)mL
1 mg / 5mL = C2
0.2 mg / mL = C2......... (because 1mg = 1000 microgram)
200 microgram / mL
- Similarly for standard 2
0.5 mg /mL * 1.5 mL = C2 * 5mL
150 microgram / mL = C2
- STANDARD 3:
0.5 mg/mL* 1mL= C2 * 5 mL
1000 microgram / mL = C2
- STANDARD 4:
0.5 mg / mL * 0.5 mL = C2 * 5mL
50 microgram / mL = C2
