# 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

#### Explanation:

This is a dilution problem.

This formula must be known/looked up:

$M 1 x V 1 = M 2 x V 2$

Given:

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:

2.50 x $V 1$ = 1.15 M x 0.350 L

$V 1$ = 0.161 L
