Too many mLs? by: Anonymous
I understand how you set up and solved the problem but although 174mL would equal a concentration of 50mg/ml, I think the max that would fit in a 10g vial is 100mL. Would it work if you added 43.5mL (87mL/2) of diluent instead?

UNDERSTANDING THE QUESTION IS THE KEY by: CHERRY
10g vial is not relevant
the question simply means how much should be added to get a conc of 50mg/ml. let the known vol and conc be C1V1 and the unknown vol and conc C2V2 C1V1=C2V2 100MG/ML*87=V2*50MG/ML V2=174ml remember how much do you to add is the question 174ml-87ml=87ml ans=87ml
hint;it became 100mg/ml when 87ml was added another 87mls will make 50mg/ml
