You want to dilute a 6.00 M HCl solution to 3.01 M. You need 500. mL of the diluted solution. How much stock solution (6.00 M HCl) must you use? Give your answer in mL.
use dilution formula
M1*V1 = M2*V2
1---> is for stock solution
2---> is for diluted solution
Given:
M1 = 6 M
M2 = 3.01 M
V2 = 500 mL
use:
M1*V1 = M2*V2
V1 = (M2 * V2) / M1
V1 = (3.01*500)/6
V1 = 251 mL
Answer: 251 mL
