What is the volume, in mL, of a 2.50M #HCl# solution that must be used in order to create a 350 mL 1.15M #HCl# solution?
0.161 L of 2.50M HCl
This is a dilution problem.
This formula must be known/looked up:
M1 = 2.50 M
V1 = ?
M2 = 1.15 M
V2 = 350 mL (must be converted to L as molarity is in mol/L)
Plug in the formula:
