Homework Sourse3 If you add 04mL of an ACh stock solution to 20 mL of Tyrod
3. If you add 0.4mL of an ACh stock solution to 20 mL of Tyrode’s and found that you now have a final [ACh] of 2 x 106M in Tyrode’s, what was the [ACh] in the original stock solution?
Solution
Answer:
0.4mL + 20 mL diluent= 20/0.2 = 50 fold dilution
Concentration of ACh = 2x 10^-6 M
Original stock = Diluted stock x Fold dilution
Original stock= 2 x 10^6M x 50
Original stock= 100 x 10^6M
