Dilution
Activity 1
A stock solution at concentration 14 mg/mL is available. 1 mL is mixed with 4 mL of distilled water. Calculate the final concentration.
Try to attempt this problem yourself. You may wish to follow the steps identified in the example provided in the previous section to solve problems like these. Type-in your answer (digits only) in the text box given below and then check your answer by clicking the 'Check Answer' button.
Use C1V1 = C2V2 with subscript 1 for stock solution, 2 for new solution.
We have C1 = 14 mg/mL, V1 = 1 mL, V2 = 5 mL and need C2
Remember to add the amount of stock solution to the amount of solvent to calculate the final volume.
