We assume that the method that made use of urea was able to recover all of the recoverable substance. The method in question is the method that makes use of water.
The total amount of substance is 43 mg/dl. The recovered amount is 25 mg/dl. The percent recovery is
(25 mg/dl / 43 mg/dl) * 100 = 58.14%

Wart remover is made of 9M of salicylic acid. If i pour 200 mL of 9M of salicylic acid into a graduated cylinder and fill it up

ArbitrLikvidat [17]

Hello!

To solve this problem we will use the dilution reaction, assuming that the number of moles of Salicylic Acid (SA) taken from the first solution will be the same as the total moles in the second solution and clear for the concentration of salicylic acid in the second solution:

$molesSA_1=molesSA_2 \\ \\ cSA_1*VSA_1=cSA_2*VSA_2 \\ \\ cSA_2= \frac{cSA_1*VSA_1}{VSA_2} = \frac{200 mL * 9M}{1000 mL}=1,8 M$

So, the concentration of Salicylic Acid in the second solution would be 1,8M

Have a nice day!
