The high concentration allows many dided solutions lo be prepared using minimal amounts of the slock solution What volume of a 621 M stock solution do you need to prepare 100 mL of a0 4161 Msoluton of HCT Express the volume to three sigincant figures with the appropriate uni Value Units y Anawers Give UpExplanation / Answer
Dilution law is given by,
M1V1 = M2V2
M1 = Initial molarity of solution = 6.21 M
V1 = Volume of Initial solution = ?
M2 = Final molarity of solution = 0.4161 M
V2 = Volume of solution required = 100mL
Now, 6.21 x V1 = 0.4161 x 100
V1 = 0.4161 x 100/6.21 = 6.70 mL
6.70 mL of stock solution has to be taken and dilute it to 100mL in standard flask to get a solution of 0.4161 M
Volume of water to be added = 100 - 6.70 = 93.30 mL
