Final answer:
The concentration of the ceftazidime solution after reconstitution with 100ml of sterile water is 10 mg/ml. This is calculated by converting 1 gram of ceftazidime to 1000 mg and dividing by the total volume of 100 ml.
Step-by-step explanation:
To determine the concentration of ceftazidime in mg/ml after reconstitution with 100ml of sterile water, we convert the amount in grams to milligrams and then divide by the volume in milliliters.
First, we have 1 gram of ceftazidime, and we know that 1 gram is equal to 1000 milligrams (mg). So, 1 gram = 1000 mg of ceftazidime.
Next, the vial is reconstituted with 100ml of sterile water, which means we now have a total volume of 100 ml.
To find the concentration in mg/ml, divide the total milligrams of ceftazidime by the total volume of the solution in milliliters:
Concentration = Total milligrams of ceftazidime / Total volume in milliliters
Concentration = 1000 mg / 100 ml = 10 mg/ml.
Therefore, the concentration of the ceftazidime solution after reconstitution is 10 mg/ml.
