True or false? To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from a 10.0 M stock solution, you should take 4.00 mL of the stock solution and add 20.0 mL of water.

Answers

Sorry I don’t know but o have to answer for pionts

False. To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from 10.0 M stock solution, 4.0 mL of the stock solution and 16.0 mL of water would be needed.  

Recall the law of diffusion that:

C1V1 = C2V2, where C1 = initial concentration, V1 = initial volume, C2 = final concentration, and V2 = final volume.

In this case, if C1 =10.0 M, V1 = ?, C2 = 2.00 M and V2 = 20.0 mL

V1 = 2 x 20/10

         = 4.0 mL

Hence, 4.0 mL of the stock solution would be taken. Since the final volume is 20.0 mL, only 16.0 mL of water would need to be added and not 20.0 mL.
