What is the amount of septocaine in a 4% 1.7 cc cartridge?

• A. 34 mg
• B. 51 mg
• C. 68 mg
• D. 85 mg

Answer: (C)

To determine the amount of septocaine (articaine) in a 4% solution contained in a 1.7 cc cartridge, we need to first understand what a 4% solution means. A 4% solution indicates that there are 4 grams of the drug in 100 milliliters of solution. Since there are 1,000 cc in a liter and 100 cc in 100 milliliters, we can calculate the amount of septocaine in a 1.7 cc cartridge. Using the percentage concentration: - A 4% solution contains 4 grams (or 4,000 mg) per 100 cc. Now, to find out how many milligrams are in 1.7 cc, we set up a proportion based on the known concentration: - If 100 cc contains 4,000 mg, then 1 cc will contain 4,000 mg / 100 cc = 40 mg. Now we multiply by the volume of the cartridge (1.7 cc): - 1.7 cc × 40 mg/cc = 68 mg. Thus, the amount of septocaine in a 4% 1.7 cc cartridge is indeed 68

Since there are 1,000 cc in a liter and 100 cc in 100 milliliters, we can calculate the amount of septocaine in a 1.7 cc cartridge.

Using the percentage concentration:

• A 4% solution contains 4 grams (or 4,000 mg) per 100 cc.

Now, to find out how many milligrams are in 1.7 cc, we set up a proportion based on the known concentration:

• If 100 cc contains 4,000 mg, then 1 cc will contain 4,000 mg / 100 cc = 40 mg.

Now we multiply by the volume of the cartridge (1.7 cc):

• 1.7 cc × 40 mg/cc = 68 mg.

Thus, the amount of septocaine in a 4% 1.7 cc cartridge is indeed 68
