If 1 mL of a 0.02% w/v isoproterenol hydrochloride solution is diluted to 10 mL with sodium chloride injection before intravenous administration, calculate the percent concentration of the diluted solution.
ANSWER:- 0.002%
The weight of isoproterenol hydrochloride solution before and after dilution should be same.
So, we use C1V1= C2V2
Here in this case, C1 = concentration of solution before dilution = 0.02 %.
V1=Volume of solution before dilution. = 1 ml
C2= concentration of solution after dilution
V2= volume of solution after solution. = 10ml
So, 0.02× 1 = C2× 10
C2 = 0.02/10 =0.002 %
So, percentage concentration of diluted solution = 0.002% W/V
