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.

Expert 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
