How many mg of mepivacaine are contained in a 3% 1.7 mL cartridge?

To calculate the amount of mepivacaine in a 3% solution contained in a 1.7 mL cartridge, you first need to understand the concentration of the solution. A 3% concentration indicates that there are 3 grams of mepivacaine per 100 mL of solution.

To find the amount in 1.7 mL, you first calculate how many grams of mepivacaine are in that volume:

1. Determine the amount of mepivacaine in 1 mL:

   • Since there are 3 grams in 100 mL, you can set up a proportion to find out how many grams are in 1 mL:
   • 3 grams / 100 mL = X grams / 1 mL
   • Solving for X gives us 0.03 grams (which is 30 mg) in 1 mL.

2. Next, multiply this amount by 1.7 mL to find the total amount of mepivacaine in the cartridge:

   • 30 mg/mL × 1.7 mL = 51 mg.

Thus, there are 51 mg of mepivacaine in
