When 100. mL of 6.00 M HCl is diluted to 300. mL, the final concentration is ________.

Marat540 [252]

Answer:

2.00 M

Explanation:

The concentration of a solution is given by

$M=\frac{m}{V}$

where

m is the mass of solute

V is the volume of the solution

At the beginning, the solution has:

M = 6.00 M is the concentration

V = 100 mL = 0.1 L is the volume

So the mass of solute (HCl) is

$m=MV=(6.00)(0.1)=0.6g$

Then, the HCL is diluted into a solution with volume of

V = 300 mL = 0.3 L

Therefore, the final concentration is:

$M=\frac{m}{V}=\frac{0.6}{0.3}=2.00 M$
