A student is conducting a lab that requires 2 M HCL In the chemical closet, there is 150 ml of 8 M HCL. How much water must be
added to stock solution to get the desired molarity for the lab?
A) 150 mL
B) 450 mL
C) 600 mL
D) 1200 mL

answer:

Therefore, you will need to have 2.5 mL of the 1% HCl solution and 7.5 mL of distilled water. In mixing the two liquids, you should remember that the order of mixing would be acid to water. So, you use a 10 mL volumetric flask . Put small amount of distilled water and add the 2.5 mL of HCl solution. Lastly, dilute with distilled water up to the 10 mL mark.
