Question

The molecular weight of the antibiotic ampicillin is 349 g/mole. Calculate how much ampicillin you would need to make 10 ml of a 1000x solution (1000-fold concentrated) for each of the following: 6. 50 μg/ml ampicillin.

Answer 1

Answer:

500 mg Ampicillin

Explanation:

given data

molecular weight = 349 g/mole

need = 10 ml of a 1000 x solution

solution        

we get here for  50 μg / mL  

here  10 ml of a 1000 x solution      

so here need to weight is =50 μg × 10 =  500μg

so we were to prepare 1000 x    

so here we get weight that is  

we should weight =  500μg × 1000  

so it is =  500 mg / 10 mL
