How many mg of bupivacaine are in a 0.5% solution within a 1.7 cc dosage?

To determine how many milligrams of bupivacaine are in a 0.5% solution within a 1.7 cc dosage, it is essential to understand the relationship between percentage concentration and the volume of the solution.

A 0.5% solution means there are 0.5 grams of bupivacaine in every 100 milliliters of the solution. To convert grams to milligrams, we recall that 1 gram is equal to 1000 milligrams. Therefore, 0.5 grams is equivalent to 500 milligrams.

Now, we can find the concentration in a more practical context. In 100 milliliters of a 0.5% solution, there are 500 mg of bupivacaine. To find out how much is present in 1.7 cc (which is equivalent to 1.7 ml), we can set up a proportion.

First, we determine how many milligrams are in 1 milliliter of the solution: 500 mg / 100 ml = 5 mg/ml.

Now, multiplying the concentration by the volume gives: 5 mg/ml x 1.7 ml = 8.5 mg.

Thus, a 0.
